The macro for_each_memcg_cache_index contains a silly yet potentially deadly mistake. Although the macro parameter is _idx, the loop tests are done over i, not _idx. This hasn't generated any problems so far, because all users use i as a loop index. However, while playing with an extension of the code I ended using another loop index and the compiler was quick to complain. Unfortunately, this is not the kind of thing that testing reveals =( Signed-off-by: Glauber Costa <glommer@parallels.com> Cc: Kamezawa Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> Cc: Johannes Weiner <hannes@cmpxchg.org> Acked-by: Michal Hocko <mhocko@suse.cz> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |
