Hi,
This patch set mostly cleanups memcg slab caches creation/destruction
paths fixing a couple of bugs in the meanwhile. The only serious change
it introduces is a rework of the sysfs layout for memcg slub caches (see
patch 7).
Changes in v2:
- do not remove cgroup name part from memcg cache
Currently, we try to arrange sysfs entries for memcg caches in the same
manner as for global caches. Apart from turning /sys/kernel/slab into a
mess when there are a lot of kmem-active memcgs created, it actually
does not work properly - we won't create more than one link to a memcg
cache in case

Otherwise, kzalloc() called from a memcg won't clear the whole object.

Suppose we are creating memcg cache A that could be merged with cache B
of the same memcg. Since any memcg cache has the same parameters as its
parent cache, parent caches PA and PB of memcg caches A and B must be
mergeable too. That means PA was merged with PB on creation or vice
versa, i.e. PA =
Currently we destroy children caches at the very beginning of
kmem_cache_destroy(). This is wrong, because the root cache will not
necessarily be destroyed in the end - if it has aliases (refcount 0),
kmem_cache_destroy() will simply decrement its refcount and return. In
this case, at best we
The way memcg_create_kmem_cache() creates the name for a memcg cache
looks rather strange: it first formats the name in the static buffer
tmp_name protected by a mutex, then passes the pointer to the buffer to
kmem_cache_create_memcg(), which finally duplicates it to the cache
name.
Let's clean
Currently, memcg_unregister_cache(), which deletes the cache being
destroyed from the memcg_slab_caches list, is called after
__kmem_cache_shutdown() (see kmem_cache_destroy()), which starts to
destroy the cache. As a result, one can access a partially destroyed
cache while traversing a
Memcg-awareness turned kmem_cache_create() into a dirty interweaving of

separate function handling memcg caches creation. Although this will
result in the two functions having several hunks of practically the same

Perhaps it makes sense to tell a bit more... We add this mask to preserve
VM_NOHUGEPAGE after fork/exec. And this is obviously affects s390, say the
result of KVM_S390_ENABLE_SIE will be preserved.
I hope this is fine, but
This toggles TIF_SYSCALL_AUDIT as needed when rules change instead of
leaving it set whenever rules might be set in the future. This reduces
syscall latency from 60ns to closer to 40ns on my laptop.

Ok, let's have another run at it. This one takes care of the relocated

boots fine here on the 32/64-bit guests.
