Would someone please be kind enough to send me the patch set? I didn't get them, and would like to test them. I have searched and searched and did manage to find: "[PATCH 2/2] slub: move synchronize_sched out of slab_mutex on shrink" And a thread about a patch 1 of 2: "Re: [PATCH 1/2] mm: memcontrol: use special workqueue for creating per-memcg caches" Where I see me as "reported by", but I guess "reported by" people don't get the e-mails. I haven't found PATCH 0/2, nor do I know if what I did find is current. ... Doug -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
