So here's a consolidated resent. Patch 1 is for an older bug that Hugh found when dealing with the mmotm bugs, Patches 2 and 3 are mmotm fixes. This doesn't address the problem 1) in Hugh's mail, which Michal Hocko also hit recently and reminded me to check these patches' status: > 1. Fix crash in release_pages() from compact_zone() from kcompactd_do_work(): > kcompactd needs to INIT_LIST_HEAD on the new freepages_held list. This one should be addressed by dropping the following from mmotm from now: mm-compaction-direct-freepage-allocation-for-async-direct-compaction.patch As there were objections from Joonsoo and Mel that I would like to try addressing before posting again.
