Subject: [PATCH 0/5] fix offline memcgroup still hold in memory
Date: Sat, 19 Jan 2019 22:30:16 -0500 [thread overview]
Message-ID: <1547955021-11520-1-git-send-email-duanxiongchun@bytedance.com> (raw)
we find that in huge memory system frequent creat creation and deletion
memcgroup make the system leave lots of offline memcgroup.we had seen 100000
unrelease offline memcgroup in our system(512G memory).
this memcgroup hold because some memory page still charged.
so we try to Multiple interval call force_empty to reclaim this memory page.
after applying those patchs,in our system,the unrelease offline memcgroup
was reduced from 100000 to 100.
Xiongchun Duan (5):
Memcgroup: force empty after memcgroup offline
Memcgroup: Add timer to trigger workqueue
Memcgroup:add a global work
Memcgroup:Implement force empty work function
Memcgroup:add cgroup fs to show offline memcgroup status
