[Devel] [PATCH vz10 17/32] mm/memcontrol: add missing inline to the mem_cgroup_fill_meminfo() stub

[Konstantin Khorenko <khorenko@virtuozzo.com>]

From: Eva Kurchatova <eva.kurchatova@virtuozzo.com>

The !CONFIG_MEMCG stub of mem_cgroup_fill_meminfo() is declared "static
void", not "static inline void", so every translation unit that includes
memcontrol.h without calling it gets an unused function - an error rather
than a warning once CONFIG_WERROR=y, as x86_64 defconfig has it:

  include/linux/memcontrol.h: error: 'mem_cgroup_fill_meminfo' defined
                              but not used [-Werror=unused-function]

Add the missing inline, like every other stub in the same #else block.

Fixes: 7710faa9d4f0 ("ve/proc: virtualize /proc/meminfo in a Container")
Feature: procfs: virtualize /proc/meminfo
