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.
