mm/memcontrol.c: make mem_cgroup_id_get_many() __maybe_unused
mem_cgroup_id_get_many() is currently used only when MMU or MEMCG_SWAP
configuration options are enabled. Having them disabled triggers the
following warning at compile time:
linux/mm/memcontrol.c:4797:13: warning: `mem_cgroup_id_get_many' defined but not used [-Wunused-function]
static void mem_cgroup_id_get_many(struct mem_cgroup *memcg, unsigned int n)
Make mem_cgroup_id_get_many() __maybe_unused to address the issue.
