-He bisected it down to commit e332f741a8dd ("mm, compaction: be selective
-about what pageblocks to clear skip hints"). The problem is that the patch
-in question was sloppy with respect to the handling of zone boundaries. In
-some instances, it was possible for PFNs outside of a zone to be examined
-and if those were not properly initialised or poisoned then it would
-trigger the VM_BUG_ON. This patch corrects the zone boundary issues when
-resetting pageblock skip hints and Mikhail reported that the bug did not
-trigger after 30 hours of testing.
