Subject: [PATCH v2 00/29] kmem limitation for memcg
Date: Fri, 11 May 2012 14:44:02 -0300 [thread overview]
Message-ID: <1336758272-24284-1-git-send-email-glommer@parallels.com> (raw)
Hello All,
This is my new take for the memcg kmem accounting.
At this point, I consider the series pretty mature - although of course,
bugs are always there...
As a disclaimer, however, I must say that the slub code is much more stressed
by me, since I know it better. If you have no more objections to the concepts
presented, the remaining edges can probably be polished in a rc cycle,
at the maintainers discretion, of course.
Otherwise, I'll be happy to address any concerns of yours.
Since last submission:
* memcgs can be properly removed.
* We are not charging based on current->mm->owner instead of current
* kmem_large allocations for slub got some fixes, specially for the free case
* A cache that is registered can be properly removed (common module case)
even if it spans memcg children. Slab had some code for that, now it works
well with both
* A new mechanism for skipping allocations is proposed (patch posted
separately already). Now instead of having kmalloc_no_account, we mark
a region as non-accountable for memcg.
I should point out again that most, if not all, of the code in the caches
are wrapped in static_key areas, meaning they will be completely patched out
until the first limit is set.
I also put a lot of effort, as you will all see, in the proper separation
of the patches, so the review process is made as easy as the complexity of
the work allows to.
