Subject: Transparent Hugepage Support #24
Date: Thu, 20 May 2010 03:04:46 +0200 [thread overview]
Message-ID: <20100520010446.GA5965@random.random> (raw)
http://git.kernel.org/?p=linux/kernel/git/andrea/aa.git;a=shortlog
http://git.kernel.org/?p=linux/kernel/git/andrea/aa.git;a=shortlog;h=refs/heads/anon_vma_chain
first: git clone git://git.kernel.org/pub/scm/linux/kernel/git/andrea/aa.git
or first: git clone --reference linux-2.6 git://git.kernel.org/pub/scm/linux/kernel/git/andrea/aa.git
later: git fetch; git checkout -f origin/master
To test the anon_vma_chain branch, simply use origin/anon_vma_chain
instead of origin/master in the above checkout. I am currently running
the origin/anon_vma_chain branch here (keeping master only in case of
troubles with the new anon-vma code, so far no problem with the
anon-vma->root shared locking design).
The tree is rebased and git pull won't work.

Diff #23 -> #24
anon-vma-lock-fix | 247 -------------
Removed and replaced by anon-vma-root shared lock.

Small change.
b/exec-migrate-race-anon_vma-chain | 196 +++++-----
Replaced with the version that keeps migrate away instead of allowing
rmap at all times (so it won't require allocations in execve).

b/root_anon_vma-vma_lock_anon_vma | 97 +++++
Rik's anon-vma-root shared locking implementation (only in
anon_vma_chain branch).
b/split_huge_page-old-anon-vma | 42 ++
anon-vma-root locking adjustment for master branch.
mincore-transhuge-anon_vma-chain | 69 ---
