# The way kmem_cache aliasing is done in the kernel is broken.
# It causes RAID 4/5/6 tests to fail.
#
# The problem with kmem_cache* is this:
# *) Assume CONFIG_SLUB is set
# 1) kmem_cache_create(name="foo-a")
# - creates new kmem_cache structure
# 2) kmem_cache_create(name="foo-b")
# - If identical cache characteristics, it will be merged with the previously
# created cache associated with "foo-a". The cache's refcount will be
# incremented and an alias will be created via sysfs_slab_alias().
# 3) kmem_cache_destroy(<ptr>)
# - Attempting to destroy cache associated with "foo-a", but instead the
# refcount is simply decremented. I don't even think the sysfs aliases are
# ever removed...
# 4) kmem_cache_create(name="foo-a")
# - This FAILS because kmem_cache_sanity_check colides with the existing
# name ("foo-a") associated with the non-removed cache.
#
# This is a problem for RAID (specifically dm-raid) because the name used
# for the kmem_cache_create is ("raid%d-%p", level, mddev). If the cache
# persists for long enough, the memory address of an old mddev will be
# reused for a new mddev - causing an identical formulation of the cache
# name. Even though kmem_cache_destory had long ago been used to delete
# the old cache, the merging of caches has cause the name and cache of that
# old instance to be preserved and causes a colision (and thus failure) in
# kmem_cache_create(). I see this regularly in testing the following
# kernels:
#
# This seems to be finaly resolved with this patch:
# http://www.redhat.com/archives/dm-devel/2014-March/msg00008.html
# so we need to put here exlusion for kernes which do trace SLUB
