mm: memcg/slab: rename slab delayed deactivation functions and fields
The delayed work/rcu deactivation infrastructure of non-root kmem_caches
can be also used for asynchronous release of these objects. Let's get rid
of the word "deactivation" in corresponding names to make the code look
better after generalization.
It's easier to make the renaming first, so that the generalized code will
look consistent from scratch.
Let's rename struct memcg_cache_params fields:
deact_fn -> work_fn
deact_rcu_head -> rcu_head
deact_work -> work
And RCU/delayed work callbacks in slab common code:
kmemcg_deactivate_rcufn -> kmemcg_rcufn
kmemcg_deactivate_workfn -> kmemcg_workfn
This patch contains no functional changes, only renamings.
