cgroup: build list of all cgroups under a given cgroupfs_root
Build a list of all cgroups anchored at cgroupfs_root->allcg_list and going through cgroup->allcg_node. The list is protected by cgroup_mutex and will be used to improve cgroup file handling. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Li Zefan <lizf@cn.fujitsu.com> |

Merge branch 's3-for-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/amit/virtio-console
Pull virtio S3 support patches from Amit Shah: "Turns out S3 is not different from S4 for virtio devices: the device is assumed to be reset, so the host and guest state are to be assumed to be out of sync upon resume. We handle the S4 case with exactly the same scenario, so just point the suspend/resume routines to the freeze/restore ones. Once that is done, we also use the PM API's macro to initialise the sleep functions. A couple of cleanups are included: there's no need for special thaw processing in the balloon driver, so that's addressed in patches 1 and 2. Testing: both S3 and S4 support have been tested using these patches using a similar method used earlier during S4 patch development: a guest is started with virtio-blk as the only disk, a virtio network card, a virtio-serial port and a virtio balloon device. Ping from guest to host, dd /dev/zero to a file on the disk, and IO from the host on the virtio-serial port, all at once, while exercising S4 and S3 (separately) were tested. They all continue to work fine after resume. virtio balloon values too were tested by inflating and deflating the balloon." Pulling from Amit, since Rusty is off getting married (and presumably shaving people). * 's3-for-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/amit/virtio-console: virtio-pci: switch to PM ops macro to initialise PM functions virtio-pci: S3 support virtio-pci: drop restore_common() virtio: drop thaw PM operation virtio: balloon: Allow stats update after restore from S4 |

Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates and fixes from Ingo Molnar:
"It's mostly fixes, but there's also two late items:
- preliminary GTK GUI support for perf report
- PMU raw event format descriptors in sysfs, to be parsed by tooling
The raw event format in sysfs is a new ABI. For example for the 'CPU'
PMU we have:
aldebaran:~> ll /sys/bus/event_source/devices/cpu/format/*
-r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/any
-r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/cmask
-r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/edge
-r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/event
-r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/inv
-r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/offcore_rsp
-r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/pc
-r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/umask
those lists of fields contain a specific format:
aldebaran:~> cat /sys/bus/event_source/devices/cpu/format/offcore_rsp
config1:0-63
So, those who wish to specify raw events can now use the following
event format:
-e cpu/cmask=1,event=2,umask=3
Most people will not want to specify any events (let alone raw
events), they'll just use whatever default event the tools use.
But for more obscure PMU events that have no cross-architecture
generic events the above syntax is more usable and a bit more
structured than specifying hex numbers."

cpuidle: add a sysfs entry to disable specific C state for debug purpose.
Some C states of new CPU might be not good. One reason is BIOS might configure them incorrectly. To help developers root cause it quickly, the patch adds a new sysfs entry, so developers could disable specific C state manually. In addition, C state might have much impact on performance tuning, as it takes much time to enter/exit C states, which might delay interrupt processing. With the new debug option, developers could check if a deep C state could impact performance and how much impact it could cause. Also add this option in Documentation/cpuidle/sysfs.txt.

This is another step closer to a common zImage for multiple platforms. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJPcpqHAAoJEIwa5zzehBx3xCMP/2evrPQyorzMBztrFB4Ry9Ol qNkSVNsemZjdtkY2dnJv+zJ/Xb0PPDU9EuBHr/SpqmVrRZEZeJND42wZK/OTFCBZ Ufi7KP1qE30daO5H3YmL+58/Ixir5fTHqggqolHhTcEYU2hnHgLBI4rIFu92kSO7 TMyrAUs14jSkTVZc6HSF83w3PfQWhMzWvspJVHQ6RebZRruETAr7v9weVMbgxcDk jQ5XJ9y73rGs2AF8bZTpUdFPzkcac7UiHn3/XyqoZs8RNCL98BGpskzhILyTARf5 X90c9mqQF+AEbb9QSDDd52uYFsJ/5COJvWdlExRI9gZZDI8Pd05ijZBR9IdGJg/B NsVsl98wvZ/zjHJ/Sb2qt5ruet7PiQUGhkshB42jVHsaWfRM030sKGYxQ8pX5Tsa cSagnfBCvAZ9VjDLkXrnEbWRNTz8LSwn9l63z0jmtm5D8+vbpMtgvtWARtuZ4RNn D8wIWoyT0ytVZnosu5441TEgCejtcKOEFzThvKDYMeMJZ/rqVkAbcznapoC2qUd4 fceNlLfQFvW7xpY1MY8mhlwC0ki4hM9MSDieaXUyefvAU/hoSp8MveVUH5UspYfb 0FpkEhzklW/g0/fuq0DJQIrMn7dajjUvVZIUQtiVQuFHOr6RUbFG5vmXuCbAyx10 PE2K4rnKz+PC8bKab7v9 =YIsn -----END PGP SIGNATURE----- Merge tag 'cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull "ARM: cleanups of io includes" from Olof Johansson: "Rob Herring has done a sweeping change cleaning up all of the mach/io.h includes, moving some of the oft-repeated macros to a common location and removing a bunch of boiler plate.

Merge branch 'for-3.4' of git://linux-nfs.org/~bfields/linux
Pull nfsd changes from Bruce Fields: Highlights: - Benny Halevy and Tigran Mkrtchyan implemented some more 4.1 features, moving us closer to a complete 4.1 implementation. - Bernd Schubert fixed a long-standing problem with readdir cookies on ext2/3/4. - Jeff Layton performed a long-overdue overhaul of the server reboot recovery code which will allow us to deprecate the current code (a rather unusual user of the vfs), and give us some needed flexibility for further improvements. - Like the client, we now support numeric uid's and gid's in the auth_sys case, allowing easier upgrades from NFSv2/v3 to v4.x. Plus miscellaneous bugfixes and cleanup. Thanks to everyone! There are also some delegation fixes waiting on vfs review that I suppose will have to wait for 3.5. With that done I think we'll finally turn off the "EXPERIMENTAL" dependency for v4 (though that's mostly symbolic as it's been on by default in distro's for a while). And the list of 4.1 todo's should be achievable for 3.5 as well: http://wiki.linux-nfs.org/wiki/index.php/Server_4.0_and_4.1_issues though we may still want a bit more experience with it before turning it on by default. * 'for-3.4' of git://linux-nfs.org/~bfields/linux: (55 commits) nfsd: only register cld pipe notifier when CONFIG_NFSD_V4 is enabled nfsd4: use auth_unix unconditionally on backchannel nfsd: fix NULL pointer dereference in cld_pipe_downcall nfsd4: memory corruption in numeric_name_to_id() sunrpc: skip portmap calls on sessions backchannel nfsd4: allow numeric idmapping nfsd: don't allow legacy client tracker init for anything but init_net nfsd: add notifier to handle mount/unmount of rpc_pipefs sb nfsd: add the infrastructure to handle the cld upcall nfsd: add a header describing upcall to nfsdcld nfsd: add a per-net-namespace struct for nfsd sunrpc: create nfsd dir in rpc_pipefs nfsd: add nfsd4_client_tracking_ops struct and a way to set it nfsd: convert nfs4_client->cl_cb_flags to a generic flags field NFSD: Fix nfs4_verifier memory alignment NFSD: Fix warnings when NFSD_DEBUG is not defined nfsd: vfs_llseek() with 32 or 64 bit offsets (hashes) nfsd: rename 'int access' to 'int may_flags' in nfsd_open() ext4: return 32/64-bit dir name hash according to usage type fs: add new FMODE flags: FMODE_32bithash and FMODE_64bithash ... |

* Support for MMC 4.5 Data Tag feature -- we tag REQ_META, so devices
that support Data Tag will provide increased throughput for metadata.
* Faster detection of card removal on I/O errors.
Drivers:
* dw_mmc now supports eMMC Power Off Notify, has PCI support, and
implements pre_req and post_req for asynchronous requests.
* omap_hsmmc now supports device tree.
* esdhc now has power management support.
* sdhci-tegra now supports Tegra30 devices.
* sdhci-spear now supports hibernation.

radix-tree: introduce bit-optimized iterator
A series of radix tree cleanups, and usage of them in the core pagecache
code.
Micro-benchmark:
lookup 14 slots (typical page-vector size)
in radix-tree there earch <step> slot filled and tagged
before/after - nsec per full scan through tree
* Intel Sandy Bridge i7-2620M 4Mb L3
New code always faster
* AMD Athlon 6000+ 2x1Mb L2, without L3
New code generally faster,
Minor degradation (marked with "*") for huge sparse trees
* i386 on Sandy Bridge
New code faster for common cases: tagged and dense trees.
Some degradations for non-tagged lookup on sparse trees.
Ideally, there might help __ffs() analog for searching first non-zero
long element in array, gcc sometimes cannot optimize this loop corretly.

pidns: add reboot_pid_ns() to handle the reboot syscall
In the case of a child pid namespace, rebooting the system does not really
makes sense. When the pid namespace is used in conjunction with the other
namespaces in order to create a linux container, the reboot syscall leads
to some problems.
A container can reboot the host. That can be fixed by dropping the
sys_reboot capability but we are unable to correctly to poweroff/
halt/reboot a container and the container stays stuck at the shutdown time
with the container's init process waiting indefinitively.
After several attempts, no solution from userspace was found to reliabily
handle the shutdown from a container.
This patch propose to make the init process of the child pid namespace to
exit with a signal status set to : SIGINT if the child pid namespace
called "halt/poweroff" and SIGHUP if the child pid namespace called
"reboot". When the reboot syscall is called and we are not in the initial
pid namespace, we kill the pid namespace for "HALT", "POWEROFF",
"RESTART", and "RESTART2". Otherwise we return EINVAL.
Returning EINVAL is also an easy way to check if this feature is supported
by the kernel when invoking another 'reboot' option like CAD.
By this way the parent process of the child pid namespace knows if it
rebooted or not and can take the right decision.
Test case:

smp: add func to IPI cpus based on parameter func
Add the on_each_cpu_cond() function that wraps on_each_cpu_mask() and calculates the cpumask of cpus to IPI by calling a function supplied as a parameter in order to determine whether to IPI each specific cpu. The function works around allocation failure of cpumask variable in CONFIG_CPUMASK_OFFSTACK=y by itereating over cpus sending an IPI a time via smp_call_function_single(). The function is useful since it allows to seperate the specific code that decided in each case whether to IPI a specific cpu for a specific request from the common boilerplate code of handling creating the mask, handling failures etc. [akpm@linux-foundation.org: s/gfpflags/gfp_flags/] [akpm@linux-foundation.org: avoid double-evaluation of `info' (per Michal), parenthesise evaluation of `cond_func'] [akpm@linux-foundation.org: s/CPU/CPUs, use all 80 cols in comment] Signed-off-by: Gilad Ben-Yossef <gilad@benyossef.com> Cc: Chris Metcalf <cmetcalf@tilera.com> Cc: Christoph Lameter <cl@linux-foundation.org> Acked-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Russell King <linux@arm.linux.org.uk> Cc: Pekka Enberg <penberg@kernel.org> Cc: Matt Mackall <mpm@selenic.com> Cc: Sasha Levin <levinsasha928@gmail.com> Cc: Rik van Riel <riel@redhat.com> Cc: Andi Kleen <andi@firstfloor.org> Cc: Alexander Viro <viro@zeniv.linux.org.uk> Cc: Avi Kivity <avi@redhat.com> Acked-by: Michal Nazarewicz <mina86@mina86.org> Cc: Kosaki Motohiro <kosaki.motohiro@gmail.com> Cc: Milton Miller <miltonm@bga.com> Reviewed-by: "Srivatsa S.

smp: introduce a generic on_each_cpu_mask() function
We have lots of infrastructure in place to partition multi-core systems such that we have a group of CPUs that are dedicated to specific task: cgroups, scheduler and interrupt affinity, and cpuisol= boot parameter. Still, kernel code will at times interrupt all CPUs in the system via IPIs for various needs. These IPIs are useful and cannot be avoided altogether, but in certain cases it is possible to interrupt only specific CPUs that have useful work to do and not the entire system. This patch set, inspired by discussions with Peter Zijlstra and Frederic Weisbecker when testing the nohz task patch set, is a first stab at trying to explore doing this by locating the places where such global IPI calls are being made and turning the global IPI into an IPI for a specific group of CPUs. The purpose of the patch set is to get feedback if this is the right way to go for dealing with this issue and indeed, if the issue is even worth dealing with at all. Based on the feedback from this patch set I plan to offer further patches that address similar issue in other code paths. This patch creates an on_each_cpu_mask() and on_each_cpu_cond() infrastructure API (the former derived from existing arch specific versions in Tile and Arm) and uses them to turn several global IPI invocation to per CPU group invocations. Core kernel: on_each_cpu_mask() calls a function on processors specified by cpumask, which may or may not include the local processor. You must not call this function with disabled interrupts or from a hardware interrupt handler or from a bottom half handler. arch/arm: Note that the generic version is a little different then the Arm one: 1. It has the mask as first parameter 2. It calls the function on the calling CPU with interrupts disabled, but this should be OK since the function is called on the other CPUs with interrupts disabled anyway. arch/tile: The API is the same as the tile private one, but the generic version also calls the function on the with interrupts disabled in UP case This is OK since the function is called on the other CPUs with interrupts disabled.

swapon: check validity of swap_flags
Most system calls taking flags first check that the flags passed in are valid, and that helps userspace to detect when new flags are supported. But swapon never did so: start checking now, to help if we ever want to support more swap_flags in future. It's difficult to get stray bits set in an int, and swapon is not widely used, so this is most unlikely to break any userspace; but we can just revert if it turns out to do so.

mm for fs: add truncate_pagecache_range()
Holepunching filesystems ext4 and xfs are using truncate_inode_pages_range but forgetting to unmap pages first (ocfs2 remembers). This is not really a bug, since races already require truncate_inode_page() to handle that case once the page is locked; but it can be very inefficient if the file being punched happens to be mapped into many vmas. Provide a drop-in replacement truncate_pagecache_range() which does the unmapping pass first, handling the awkward mismatch between arguments to truncate_inode_pages_range() and arguments to unmap_mapping_range(). Note that holepunching does not unmap privately COWed pages in the range: POSIX requires that we do so when truncating, but it's hard to justify, difficult to implement without an i_size cutoff, and no filesystem is attempting to implement it.

Pull "Disintegrate and delete asm/system.h" from David Howells:
"Here are a bunch of patches to disintegrate asm/system.h into a set of
separate bits to relieve the problem of circular inclusion
dependencies.
I've built all the working defconfigs from all the arches that I can
and made sure that they don't break.
The reason for these patches is that I recently encountered a circular
dependency problem that came about when I produced some patches to
optimise get_order() by rewriting it to use ilog2().
This uses bitops - and on the SH arch asm/bitops.h drags in
asm-generic/get_order.h by a circuituous route involving asm/system.h.
The main difficulty seems to be asm/system.h. It holds a number of
low level bits with no/few dependencies that are commonly used (eg.
memory barriers) and a number of bits with more dependencies that
aren't used in many places (eg. switch_to()).
These patches break asm/system.h up into the following core pieces:
(1) asm/barrier.h
Move memory barriers here. This already done for MIPS and Alpha.
(2) asm/switch_to.h
Move switch_to() and related stuff here.
(3) asm/exec.h
Move arch_align_stack() here. Other process execution related bits
could perhaps go here from asm/processor.h.
(4) asm/cmpxchg.h
Move xchg() and cmpxchg() here as they're full word atomic ops and
frequently used by atomic_xchg() and atomic_cmpxchg().
(5) asm/bug.h
Move die() and related bits.
(6) asm/auxvec.h
Move AT_VECTOR_SIZE_ARCH here.
Other arch headers are created as needed on a per-arch basis."
Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that. We'll find out anything that got broken and fix it..
