mm: compaction: make compact_control order signed
"order" is -1 when compacting via /proc/sys/vm/compact_memory. Making it unsigned causes a bug in __compact_pgdat() when we test: if (cc->order < 0 || !compaction_deferred(zone, cc->order)) compact_zone(zone, cc); [akpm@linux-foundation.org: make __compact_pgdat()'s comparison match other code sites] Signed-off-by:Dan Carpenter <dan.carpenter@oracle.com> Cc: Mel Gorman <mel@csn.ul.ie> Cc: Minchan Kim <minchan@kernel.org> Reviewed-by:
