This is a set of patches which I'm now testing, and it seems it passed
small test. So I post this.
Some are bug fixes and other are clean ups but I think these are for 2.6.38.
Brief decription
[1/7] remove buggy comment and use better name for mem_cgroup_move_parent()
The fixes for mem_cgroup_move_parent() is already in mainline, this is
an add-on.
[2/7] a bug fix for a new function mem_cgroup_split_huge_fixup(),
which was recently merged.
[3/7] prepare for fixes in [4/7],[5/7]. This is an enhancement of function
which is used now.
[4/7] fix mem_cgroup_charge() for THP. By this, memory cgroup's charge function
will handle THP request in sane way.
[5/7] fix khugepaged scan condition for memcg.
This is a fix for hang of processes under small/buzy memory cgroup.
[6/7] rename vairable names to be page_size, nr_pages, bytes rather than
ambiguous names.
[7/7] some memcg function requires the caller to initialize variable
before call. It's ugly and fix it.
I think patch 1,2,3,4,5 is urgent ones. But I think patch "5" needs some
good review. But without "5", stress-test on small memory cgroup will not
run succesfully.
Thanks,
-Kame
