mm: kmem: rename memcg_kmem_(un)charge() into memcg_kmem_(un)charge_page()
Rename (__)memcg_kmem_(un)charge() into (__)memcg_kmem_(un)charge_page() to better reflect what they are actually doing: 1) call __memcg_kmem_(un)charge_memcg() to actually charge or uncharge the current memcg 2) set or clear the PageKmemcg flag Signed-off-by: Roman Gushchin <guro@fb.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Reviewed-by: Shakeel Butt <shakeelb@google.com> Acked-by: Johannes Weiner <hannes@cmpxchg.org> Cc: Michal Hocko <mhocko@kernel.org> Cc: Vladimir Davydov <vdavydov.dev@gmail.com> Link: http://lkml.kernel.org/r/20200109202659.752357-4-guro@fb.com Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
