The REPORT ZONES buffer size is currently limited by the HBA's maximum
segment count to ensure the buffer can be mapped. However, the block
layer further limits the number of iovec entries to 1024 when allocating
a bio.
To avoid allocation of buffers too large to be mapped, further restrict
the maximum buffer size to BIO_MAX_INLINE_VECS.
Replace the UIO_MAXIOV symbolic name with the more contextually
appropriate BIO_MAX_INLINE_VECS.

scsi: ufs: core: Remove redundant query_complete trace
scsi: myrb: Fix spelling mistake "statux" -> "status"
Don Brace <don.brace@microchip.com> says:
These patches are based on Martin Petersen's 6.16/scsi-queue tree
https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git
6.16/scsi-queue
There are two main functional changes in this patch series:
smartpqi-take-drives-offline-when-controller-is-offline
smartpqi-fix-smp_processor_id-call-trace-for-preemptible-kernels
The other two patches add PCI-IDs for new controllers and change the
driver version.
This set of changes consists of:
* smartpqi-take-drives-offline-when-controller-is-offline
On rare occasions, the controller can lock up and the driver was
removing the controller instance from OS but leaving the
drives exposed and their state was still 'running'.
This patch sets the drive state as 'offline' to avoid confusion.
* smartpqi-add-new-pci_ids
Add support for more PCI devices.
* smartpqi-enhance_wwid-logging-logic
Cosmetic change for logging WWIDs for NVMe devices and for drives
that support the extended format.
* smartpqi-fix-smp_processor_id-call-trace-for-preemptible-kernels
When preemption is enabled, there are call traces in the console
logs which are annoying. The call trace mentions using
smp_processor_id(). Since the driver is only using this function call
when accessing a per_cpu variable, we changed the call to
raw_smp_processor_id(). This patch was written by
Yi Zhang <yi.zhang@redhat.com> and I am posting it on his behalf.
* smartpqi-update-driver-version-to-2.1.34-035
No functional changes.

A PCI function reset implies a temporary disappearance of a fc_rport.
So, call lpfc_scsi_dev_block(), which sets all mapped fc_rports into the
temporary FC_PORTSTATE_BLOCKED state. Once PCI function reset completes
and link reinitialized, the fc_rport is rediscovered and
FC_PORTSTATE_BLOCKED state is removed.

In lpfc_check_sli_ndlp(), the get_job_els_rsp64_did remote_id assignment
does not apply for GEN_REQUEST64 commands as it only has meaning for a
ELS_REQUEST64 command. So, if (iocb->ndlp == ndlp) is false, we could
erroneously return the wrong value. Fix by replacing the fallthrough
statement with a break statement before the remote_id check.

It turns out that there are no platforms that have PCI but don't have an
MMU, so adding a Kconfig dependency on CONFIG_PCI simplifies build testing
kernels for those platforms a lot, and avoids a lot of inadvertent build
regressions.
Add a dependency for CONFIG_PCI and remove all the ones for PCI specific
device drivers that are currently marked not having it.
There are a few platforms that have an optional MMU, but they usually
cannot have PCI at all. The one exception is Coldfire MCF54xx, but this is
mainly for historic reasons, and anyone using those chips should really use
the MMU these days.

With ATA devices supporting the CDL feature, using CDL requires that the
feature be enabled with a SET FEATURES command. This command is issued
as the translated command for the MODE SELECT command issued by
scsi_cdl_enable() when the user enables CDL through the device
cdl_enable sysfs attribute.
However, the implementation of scsi_cdl_enable() always issues a MODE
SELECT command for ATA devices when the enable argument is true, even if
CDL is already enabled on the device. While this does not cause any
issue with using CDL descriptors with read/write commands (the CDL
feature will be enabled on the drive), issuing the MODE SELECT command
even when the device CDL feature is already enabled will cause a reset
of the ATA device CDL statistics log page (as defined in ACS, any CDL
enable action must reset the device statistics).
Avoid this needless actions (and the implied statistics log page reset)
by modifying scsi_cdl_enable() to issue the MODE SELECT command to
enable CDL if and only if CDL is not reported as already enabled on the
device.
And while at it, simplify the initialization of the is_ata boolean
variable and move the declaration of the scsi mode data and sense header
variables to within the scope of ATA device handling.

In commit 21c7e97247 ("scsi: hisi_sas: Disable SATA disk phy for severe
I_T nexus reset failure"), if the softreset fails upon certain
conditions, the PHY connected to the disk is disabled directly. Manual
recovery is required, which is inconvenient for users in actual use.
In addition, SATA disks do not support simultaneous connection of multiple
hosts. Therefore, when multiple controllers are connected to a SATA disk
at the same time, the controller which is connected later failed to issue
an ATA softreset to the SATA disk. As a result, the PHY associated with
the disk is disabled and cannot be automatically recovered.
Now that, we will not focus on the execution result of softreset. No
matter whether the execution is successful or not, we will directly carry
out I_T_nexus_reset.

strncpy() is deprecated for NUL-terminated destination buffers; use
strscpy() instead.
Since sli_config_cmd_init() already zeroes out the destination buffers,
the potential NUL-padding by strncpy() is unnecessary. strscpy() copies
only the required characters and guarantees NUL-termination.
And since all three destination buffers have a fixed length, strscpy()
automatically determines their size using sizeof() when the argument is
omitted. This makes any explicit sizeof() calls unnecessary.
The source strings are also NUL-terminated and meet the __must_be_cstr()
requirement of strscpy().

The smartpqi driver checks the reset_devices variable to determine
whether special adjustments need to be made for kdump. This has the
effect that after a regular kexec reboot, some driver parameters such as
max_transfer_size are much lower than usual. More importantly, kexec
reboot tests have revealed memory corruption caused by the driver log
being written to system memory after a kexec.
Fix this by testing is_kdump_kernel() rather than reset_devices where
appropriate.

when a SATA disk is directly connected the SAS controller determines the
disk to which I/Os are delivered based on the port ID in the DQ entry.
When many phys are disconnected and reconnect, the port ID of phys were
changed and used by other link, resulting in I/O being sent to incorrect
disk. Data inconsistency on the SATA disk may occur during I/O retries
using the old port ID. So enable force phy, then force the command to be
executed in a certain phy, and if the actual phy ID of the port does not
match the phy configured in the command, the chip will stop delivering the
I/O to disk.

Commit 32566a6f1a ("scsi: lpfc: Remove NLP_RELEASE_RPI flag from nodelist
structure") introduced a regression with SLI-3 adapters (e.g. LPe12000 8Gb)
where a Link Down / Link Up such as caused by disabling an host FC switch
port would result in the devices remaining in the transport-offline state
and multipath reporting them as failed. This problem was not seen with
newer SLI-4 adapters.
The problem was caused by portions of the patch which removed the functions
__lpfc_sli_rpi_release() and lpfc_sli_rpi_release() and all their callers.
This was presumably because with the removal of the NLP_RELEASE_RPI flag
there was no need to free the rpi.
However, __lpfc_sli_rpi_release() and lpfc_sli_rpi_release() which calls it
reset the NLP_UNREG_INP flag. And, lpfc_sli_def_mbox_cmpl() has a path
where __lpfc_sli_rpi_release() was called in a particular case where
NLP_UNREG_INP was not otherwise cleared because of other conditions.
Restoring the else clause of this conditional and simply clearing the
NLP_UNREG_INP flag appears to resolve the problem with SLI-3 adapters. It
should be noted that the code path in question is not specific to SLI-3,
but there are other SLI-4 code paths which may have masked the issue.

number of bytes will lead to a read overflow. Divide by 4 to get the
correct value.

Function stop_qc_helper() is called while the debug_scsi_cmd lock is held,
and from here we may call cancel_work_sync(), which may sleep.
Sleeping in atomic sections is not allowed.
Hence change the cancel_work_sync() call into a cancel_work() call.
However now it is not possible to know if the work callback is running when
we return. This is relevant for eh_abort_handler handling, as the semantics
of that callback are that success means that we do not keep a reference to
the scsi_cmnd - now this is not possible. So return FAIL when we are unsure
if the callback still running.

Admin reply processing can be called from multiple contexts. The driver
uses an atomic flag for synchronization among multiple threads/context for
draining the admin replies.
Upon entering the admin processing routine, the driver will set the atomic
flag and start reply processing. When exiting the routine, the driver
resets the flag. However, there is a race condition when one thread (Thread
1) has processed replies and is about to reset the flag but in the meantime
few more replies are posted and another thread (Thread 2) is called to
process replies. Since the synchronization flag is still set, Thread 2 will
return without processing replies and those new replies will not be
flushed.
Make the watchdog thread monitor cases where admin ISR/poll call returns
due to another thread processing admin replies. If such an instance is
found, make driver call admin ISR to drain replies (if any).

Kai Mäkisara <Kai.Makisara@kolumbus.fi> says:
Currently, the scsi_debug driver can create tape devices and the st
driver attaches to those. Nothing much can be done with the tape devices
because scsi_debug does not have support for the tape-specific commands
and features. These patches add some more tape support to the scsi_debug
driver. The end result is simulated drives with a tape having one or two
partitions (one partition is created initially).
The tape is implemented as fixed number (10 000) of 8-byte units.
The first four bytes of a unit contain the type of the unit (data
block, filemark or end-of-data mark). If the units is a data block,
the first four bytes also contain the block length and the remaining
four bytes the first bytes of written data. This allows the user
to use tags to see that the read block is what it was supposed to be.
The following SCSI operations are added or modified:
FORMAT MEDIUM
- added
LOCATE
- added
MODE SELECT
- modified to allow use without page(s) (just header and block descriptor)
- store density and block size
- partition page added
MODE SENSE
- modified to allow use without page(s) (just header and block descriptor)
- set density and block size
- partition page added
READ BLOCK LIMITS
- added
READ POSITION
- added
READ
- added tape support for READ (6)
REWIND
- modified to set the tape position
SPACE
- added
START STOP (LOAD)
- modified to return New Medium Unit Attention if tape loaded (not
according to the standard, but enables testing this UA)
WRITE
- added tape support for WRITE (6)
WRITE FILEMARKS
- added

lpfc_next_online_cpu() opencodes cpumask_next_and_wrap() by using
a for-loop. Use it and make the lpfc_next_online_cpu() a plain
one-liner.
While there, rework lpfc_next_present_cpu() similarly. Notice that
cpumask_next() followed by cpumask_first() in the worst case of an
empty mask may traverse the mask twice. Cpumask_next_wrap() takes
