slab: introduce __kmemcg_cache_deactivate()
__kmem_cache_shrink() is called with %true @deactivate only for memcg
caches. Remove @deactivate from __kmem_cache_shrink() and introduce
__kmemcg_cache_deactivate() instead. Each memcg-supporting allocator
should implement it and it should deactivate and drain the cache.
This is to allow memcg cache deactivation behavior to further deviate
from simple shrinking without messing up __kmem_cache_shrink().
This is pure reorganization and doesn't introduce any observable
behavior changes.
v2: Dropped unnecessary ifdef in mm/slab.h as suggested by Vladimir.
