Subject[PATCH v2 0/6] mm: memcg: kmem API cleanup
Date
This patchset aims to clean up the kernel memory charging API.
It doesn't bring any functional changes, just removes unused
arguments, renames some functions and fixes some comments.

Currently it's not obvious which functions are most basic
(memcg_kmem_(un)charge_memcg()) and which are based on them
(memcg_kmem_(un)charge()). The patchset renames these functions
and removes unused arguments:

TL;DR:
was:
memcg_kmem_charge_memcg(page, gfp, order, memcg)
memcg_kmem_uncharge_memcg(memcg, nr_pages)
memcg_kmem_charge(page, gfp, order)
memcg_kmem_uncharge(page, order)

now:
memcg_kmem_charge(memcg, gfp, nr_pages)
memcg_kmem_uncharge(memcg, nr_pages)
memcg_kmem_charge_page(page, gfp, order)
memcg_kmem_uncharge_page(page, order)


v2:
1) Dropped the first patch, which was incorrect. Thanks, Andrew!


Roman Gushchin (6):
mm: kmem: cleanup (__)memcg_kmem_charge_memcg() arguments
mm: kmem: cleanup memcg_kmem_uncharge_memcg() arguments
mm: kmem: rename memcg_kmem_(un)charge() into
memcg_kmem_(un)charge_page()
mm: kmem: switch to nr_pages in (__)memcg_kmem_charge_memcg()
mm: memcg/slab: cache page number in memcg_(un)charge_slab()
mm: kmem: rename (__)memcg_kmem_(un)charge_memcg() to
__memcg_kmem_(un)charge()
