[PATCH 2/3] mm: slab: rename (un)charge_slab_page() to (un)account_slab_page()

From: Roman Gushchin
Date: Tue Jul 07 2020 - 13:36:36 EST


charge_slab_page() and uncharge_slab_page() are not related anymore
to memcg charging and uncharging. In order to make their names
less confusing, let's rename them to account_slab_page() and
unaccount_slab_page() respectively.
