Revision c81758fbe0fdbbc0c74b37798f55bd9c91d5c068 authored by Minchan Kim on 21 August 2012, 23:16:03 UTC, committed by Linus Torvalds on 21 August 2012, 23:45:03 UTC
Commit aff622495c9a ("vmscan: only defer compaction for failed order and higher") fixed bad deferring policy but made mistake about checking compact_order_failed in __compact_pgdat(). So it can't update compact_order_failed with the new order. This ends up preventing correct operation of policy deferral. This patch fixes it.
