Merge tag 'mm-compaction-5.1-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux
Pull mm/compaction fixes from Mel Gorman: "The merge window for 5.1 introduced a number of compaction-related patches. with intermittent reports of corruption and functional issues. The bugs are due to sloopy checking of zone boundaries and a corner case where invalid indexes are used to access the free lists. Reports are not common but at least two users and 0-day have tripped over them. There is a chance that one of the syzbot reports are related but it has not been confirmed properly. The normal submission path is with Andrew but there have been some delays and I consider them urgent enough that they should be picked up before RC4 to avoid duplicate reports. All of these have been successfully tested on older RC windows. This will make this branch look like a rebase but in fact, they've simply been lifted again from Andrew's tree and placed on a fresh branch. I've no reason to believe that this has invalidated the testing given the lack of change in compaction and the nature of the fixes" * tag 'mm-compaction-5.1-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux: mm/compaction.c: abort search if isolation fails mm/compaction.c: correct zone boundary handling when resetting pageblock skip hints
