| |
Hi.
Current(I'm testing 2008-12-16-15-50 with some patches, though) memcg have MEM_CGROUP_ZSTAT underflow problem.
How to reproduce: - make a directory, set mem.limit. - run some programs exceeding mem.limit. - make another directory, and all the tasks in old directory to new one. - New directory's "inactive_anon" in memory.stat underflows.
From my investigation: - This problem seems to happen only when swapping anonymous pages. It seems not to happen about shmem. - After removing memcg-fix-swap-accounting-leak-v3.patch(and of course memcg-fix-swap-accounting-leak-doc-fix.patch), this problem doesn't happen.
Thoughts?
Thanks, Daisuke Nishimura.
