I'll take your changelog for aa.git thanks! And the non trivial stuff was documented in the code too. So now in aa.git I've two branches, master -> old-anon_vma, anon_vma_chain -> new-anon_vma. anon_vma_chain starts with Rik's patch 1/2 and then this patch. old-anon_vma starts with backout-anon-vma and then this patch 2 backported to old anon-vma code. After the removal of all vma->anon_vma->lock usages from THP code, and switching to a slower get_page() spin_unlock(page_table_lock) page_lock_anon_vma(page) model, the anon_vma_chain branch has a chance to be as solid as the master branch. anon_vma_chain branch can be pulled from mainline branches too. The master branch is also not using anymore any vma->anon_vma->lock even if it still could and it'd be a bit faster, to give more testing to the anon_vma_chain code. You can see the difference with "git diff master anon_vma_chain". http://git.kernel.org/?p=linux/kernel/git/andrea/aa.git;a=summary http://git.kernel.org/?p=linux/kernel/git/andrea/aa.git;a=shortlog;h=refs/heads/anon_vma_chain This should be THP-23 and THP-23-anon_vma_chain tags, I'll do proper release soon. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
