Revision a582a738c763e106f47eab24b8146c698a9c700b authored by Shaohua Li on 15 June 2011, 22:08:49 UTC, committed by Linus Torvalds on 16 June 2011, 03:04:02 UTC
fragmentation_index() returns -1000 when the allocation might succeed This doesn't match the comment and code in compaction_suitable(). I thought compaction_suitable should return COMPACT_PARTIAL in -1000 case, because in this case allocation could succeed depending on watermarks. The impact of this is that compaction starts and compact_finished() is called which rechecks the watermarks and the free lists. It should have the same result in that compaction should not start but is more expensive.
