 * of the shrinker callback function is required.  Only the callback
 * function needs to be passed.
 *
 *   SPL_SHRINKER_CALLBACK_FWD_DECLARE(shrinker_callback);
 *
 * SPL_SHRINKER_CALLBACK_WRAPPER is used to declare the callback function
 * which is registered with the shrinker.  This function will call your
 * custom shrinker which must use the following prototype.  Notice the
 * leading __'s, these must be appended to the callback_function name.
 *
 *   int  __shrinker_callback(struct shrinker *, struct shrink_control *)
 *   SPL_SHRINKER_CALLBACK_WRAPPER(shrinker_callback);a
 *
 *
 * Example:
 *
 * SPL_SHRINKER_CALLBACK_FWD_DECLARE(my_shrinker_fn);
 * SPL_SHRINKER_DECLARE(my_shrinker, my_shrinker_fn, 1);
 *
 * static int
 * __my_shrinker_fn(struct shrinker *shrink, struct shrink_control *sc)
 * {
 *	if (sc->nr_to_scan) {
 *		...scan objects in the cache and reclaim them...
 *	}
 *
 *	...calculate number of objects in the cache...
 *
 *	return (number of objects in the cache);
 * }
 * SPL_SHRINKER_CALLBACK_WRAPPER(my_shrinker_fn);

 /*
 * vmem_* is an interface to a low level arena-based memory allocator on
 * Illumos that is used to allocate virtual address space. The kmem SLAB
 * allocator allocates slabs from it. Then the generic allocation functions
 * kmem_{alloc,zalloc,free}() are layered on top of SLAB allocators.
 *
 * On Linux, the primary means of doing allocations is via kmalloc(), which
 * is similarly layered on top of something called the buddy allocator. The
 * buddy allocator is not available to kernel modules, it uses physical
 * memory addresses rather than virtual memory addresses and is prone to
 * fragmentation.
 *
 * Linux sets aside a relatively small address space for in-kernel virtual
 * memory from which allocations can be done using vmalloc().  It might seem
 * like a good idea to use vmalloc() to implement something similar to
 * Illumos' allocator. However, this has the following problems:
 *
 * 1. Page directory table allocations are hard coded to use GFP_KERNEL.
 *    Consequently, any KM_PUSHPAGE or KM_NOSLEEP allocations done using
 *    vmalloc() will not have proper semantics.
 *
 * 2. Address space exhaustion is a real issue on 32-bit platforms where
 *    only a few 100MB are available. The kernel will handle it by spinning
 *    when it runs out of address space.
 *
 * 3. All vmalloc() allocations and frees are protected by a single global
 *    lock which serializes all allocations.
 *
 * 4. Accessing /proc/meminfo and /proc/vmallocinfo will iterate the entire
 *    list. The former will sum the allocations while the latter will print
 *    them to user space in a way that user space can keep the lock held
 *    indefinitely.  When the total number of mapped allocations is large
 *    (several 100,000) a large amount of time will be spent waiting on locks.
 *
 * 5. Linux has a wait_on_bit() locking primitive that assumes physical
 *    memory is used, it simply does not work on virtual memory.  Certain
 *    Linux structures (e.g. the superblock) use them and might be embedded
 *    into a structure from Illumos.  This makes using Linux virtual memory
 *    unsafe in certain situations.
 *
 * It follows that we cannot obtain identical semantics to those on Illumos.
 * Consequently, we implement the kmem_{alloc,zalloc,free}() functions in
 * such a way that they can be used as drop-in replacements for small vmem_*
 * allocations (8MB in size or smaller) and map vmem_{alloc,zalloc,free}()
 * to them.

 \fBspl_kmem_cache_expire\fR (uint)
 .ad
 .RS 12n
 Cache expiration is part of default Illumos cache behavior.  The idea is
 that objects in magazines which have not been recently accessed should be
 returned to the slabs periodically.  This is known as cache aging and
 when enabled objects will be typically returned after 15 seconds.
 .sp
 On the other hand Linux slabs are designed to never move objects back to
 the slabs unless there is memory pressure.  This is possible because under
 Linux the cache will be notified when memory is low and objects can be
 released.
 .sp
 By default only the Linux method is enabled.  It has been shown to improve
 responsiveness on low memory systems and not negatively impact the performance
 of systems with more memory.  This policy may be changed by setting the
 \fBspl_kmem_cache_expire\fR bit mask as follows, both policies may be enabled
 concurrently.
 .sp

 Default value: \fB0x02\fR
 .RE
 .sp
 .ne 2
 .na
 \fBspl_kmem_cache_reclaim\fR (uint)
 .ad
 .RS 12n
 When this is set it prevents Linux from being able to rapidly reclaim all the
 memory held by the kmem caches.  This may be useful in circumstances where
 it's preferable that Linux reclaim memory from some other subsystem first.
 Setting this will increase the likelihood out of memory events on a memory
 constrained system.
 .sp
 Default value: \fB0\fR
 .RE
 .sp
 .ne 2
 .na
 \fBspl_kmem_cache_obj_per_slab\fR (uint)
 .ad
 .RS 12n
 The preferred number of objects per slab in the cache.   In general, a larger
 value will increase the caches memory footprint while decreasing the time
 required to perform an allocation.  Conversely, a smaller value will minimize
 the footprint and improve cache reclaim time but individual allocations may
 take longer.

 Default value: \fB8\fR
 .RE
 .sp
 .ne 2
 .na
 \fBspl_kmem_cache_obj_per_slab_min\fR (uint)
 .ad
 .RS 12n
 The minimum number of objects allowed per slab.  Normally slabs will contain
 \fBspl_kmem_cache_obj_per_slab\fR objects but for caches that contain very
 large objects it's desirable to only have a few, or even just one, object per
 slab.
 .sp
 Default value: \fB1\fR
 .RE
 .sp
 .ne 2
 .na
 \fBspl_kmem_cache_max_size\fR (uint)
 .ad
 .RS 12n
 The maximum size of a kmem cache slab in MiB.  This effectively limits
 the maximum cache object size to \fBspl_kmem_cache_max_size\fR /
 \fBspl_kmem_cache_obj_per_slab\fR.  Caches may not be created with
 object sized larger than this limit.
 .sp
 Default value: \fB32 (64-bit) or 4 (32-bit)\fR
 .RE
 .sp
 .ne 2
 .na
 \fBspl_kmem_cache_slab_limit\fR (uint)
 .ad
 .RS 12n
 For small objects the Linux slab allocator should be used to make the most
 efficient use of the memory.  However, large objects are not supported by
 the Linux slab and therefore the SPL implementation is preferred.  This
 value is used to determine the cutoff between a small and large object.
 .sp
 Objects of \fBspl_kmem_cache_slab_limit\fR or smaller will be allocated
 using the Linux slab allocator, large objects use the SPL allocator.  A
 cutoff of 16K was determined to be optimal for architectures using 4K pages.
 .sp
 Default value: \fB16,384\fR
 .RE
 .sp
 .ne 2
 .na
 \fBspl_kmem_cache_kmem_limit\fR (uint)
 .ad
 .RS 12n
 Depending on the size of a cache object it may be backed by kmalloc()'d
 or vmalloc()'d memory.  This is because the size of the required allocation
 greatly impacts the best way to allocate the memory.
 .sp
 When objects are small and only a small number of memory pages need to be
 allocated, ideally just one, then kmalloc() is very efficient.  However,
 when allocating multiple pages with kmalloc() it gets increasingly expensive
 because the pages must be physically contiguous.
 .sp
 For this reason we shift to vmalloc() for slabs of large objects which
 which removes the need for contiguous pages.  We cannot use vmalloc() in
 all cases because there is significant locking overhead involved.  This
 function takes a single global lock over the entire virtual address range
 which serializes all allocations.  Using slightly different allocation
 functions for small and large objects allows us to handle a wide range of
 object sizes.
 .sh
 The \fBspl_kmem_cache_kmem_limit\fR value is used to determine this cutoff
 size.  One quarter the PAGE_SIZE is used as the default value because
 \fBspl_kmem_cache_obj_per_slab\fR defaults to 16.  This means that at
 most we will need to allocate four contiguous pages.
 .sp
 Default value: \fBPAGE_SIZE/4\fR
 .RE
 .sp
 .ne 2
 .na
 \fBspl_kmem_alloc_warn\fR (uint)
 .ad
 .RS 12n
 As a general rule kmem_alloc() allocations should be small, preferably
 just a few pages since they must by physically contiguous.  Therefore, a
 rate limited warning will be printed to the console for any kmem_alloc()
 which exceeds a reasonable threshold.
 .sp
 The default warning threshold is set to eight pages but capped at 32K to
 accommodate systems using large pages.  This value was selected to be small
 enough to ensure the largest allocations are quickly noticed and fixed.
 But large enough to avoid logging any warnings when a allocation size is
 larger than optimal but not a serious concern.  Since this value is tunable,
 developers are encouraged to set it lower when testing so any new largish
 allocations are quickly caught.  These warnings may be disabled by setting
 the threshold to zero.
 .sp
 Default value: \fB32,768\fR
 .RE
 .sp
 .ne 2
 .na
 \fBspl_kmem_alloc_max\fR (uint)
 .ad
 .RS 12n
 Large kmem_alloc() allocations will fail if they exceed KMALLOC_MAX_SIZE.
 Allocations which are marginally smaller than this limit may succeed but
 should still be avoided due to the expense of locating a contiguous range
 of free pages.  Therefore, a maximum kmem size with reasonable safely
 margin of 4x is set.  Kmem_alloc() allocations larger than this maximum
 will quickly fail.  Vmem_alloc() allocations less than or equal to this
 value will use kmalloc(), but shift to vmalloc() when exceeding this value.
 .sp
 Default value: \fBKMALLOC_MAX_SIZE/4\fR
 .RE
 .sp
 .ne 2
 .na
 \fBspl_kmem_cache_magazine_size\fR (uint)
 .ad
 .RS 12n
 Cache magazines are an optimization designed to minimize the cost of
 allocating memory.  They do this by keeping a per-cpu cache of recently
 freed objects, which can then be reallocated without taking a lock. This
 can improve performance on highly contended caches.  However, because
 objects in magazines will prevent otherwise empty slabs from being
 immediately released this may not be ideal for low memory machines.
 .sp
 For this reason \fBspl_kmem_cache_magazine_size\fR can be used to set a
 maximum magazine size.  When this value is set to 0 the magazine size will
 be automatically determined based on the object size.  Otherwise magazines
 will be limited to 2-256 objects per magazine (i.e per cpu).  Magazines
 may never be entirely disabled in this implementation.
 .sp
 Default value: \fB0\fR
 .RE
 .sp
 .ne 2
 .na
 \fBspl_hostid\fR (ulong)
 .ad
 .RS 12n
 The system hostid, when set this can be used to uniquely identify a system.
 By default this value is set to zero which indicates the hostid is disabled.
 It can be explicitly enabled by placing a unique non-zero value in
 \fB/etc/hostid/\fR.
 .sp
 Default value: \fB0\fR
 .RE
 .sp
 .ne 2
 .na
 \fBspl_hostid_path\fR (charp)
 .ad
 .RS 12n
 The expected path to locate the system hostid when specified.  This value
 may be overridden for non-standard configurations.
 .sp
 Default value: \fB/etc/hostid\fR
 .RE
 .sp
 .ne 2
 .na
 \fBspl_taskq_thread_bind\fR (int)
 .ad
 .RS 12n
 Bind taskq threads to specific CPUs.  When enabled all taskq threads will
 be distributed evenly  over the available CPUs.  By default, this behavior
 is disabled to allow the Linux scheduler the maximum flexibility to determine
 where a thread should run.
