Subject: memcg: get rid of extern for functions in memcontrol.h
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=64219994898c8689c3d57668996f476f8c2d398c;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

memcg: get rid of extern for functions in memcontrol.h

Most of the exported functions in this header are not marked extern so
change the rest to follow the same style.
