From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: memcg: include linux/mm.h
A recent change to the memcg code added a call to virt_to_head_page, which
is declared in linux/mm.h, but this is not necessarily included here and
will cause compile errors:
include/linux/memcontrol.h:841:9: error: implicit declaration of function 'virt_to_head_page' [-Werror=implicit-function-declaration]
This adds an explicit include statement that gets rid of the error.
