#     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"
