I merged patches 1-7 to "sleb/core" branch of slab.git if people want to test them: http://git.kernel.org/?p=linux/kernel/git/penberg/slab-2.6.git;a=shortlog;h=refs/heads/sleb/core I didn't put them in linux-next for obvious reasons. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
