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.
