From: Roman Gushchin <guro@xxxxxx> Subject: mm: slab: rename (un)charge_slab_page() to (un)account_slab_page() 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.
