The patch titled Subject: mm: kmem: make __memcg_kmem_(un)charge static has been removed from the -mm tree. Its filename was mm-kmem-make-__memcg_kmem_uncharge-static.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Roman Gushchin <guro@xxxxxx> Subject: mm: kmem: make __memcg_kmem_(un)charge static I've noticed that __memcg_kmem_charge() and __memcg_kmem_uncharge() are not used anywhere except memcontrol.c. Yet they are not declared as non-static and are declared in memcontrol.h. This patch makes them static.
