Subject: [PATCH -mm 0/5] memcg: performance improvement v4
Hi, this version is against 2.6.26-rc2-mm1...much easier to try ;)
please test.
Major changes from v3.
- shmem handling is fixed.
- dropped drop_pages patch (1/6 in v3). It will be rescheduled.
- applied comments (Thanks!)
brief test result on x86-64 (2core) system is attached below but it seems
better to be tested on bigger system/bigger benchmark.
(But I can't do now, sorry)
Patch Description
1/5 ... remove refcnt fron page_cgroup patch (shmem handling is fixed)
2/5 ... swapcache handling patch
3/5 ... add helper function for shmem's memory reclaim patch
4/5 ... optimize by likely/unlikely ppatch
5/5 ... remove redundunt check patch (shmem handling is fixed.)
Unix bench result.
== 2.6.26-rc2-mm1 + memory resource controller
