+ commit ab00ddd802f80e31fc9639c652d736fe3913feae upstream. + When running mm selftest to verify mm patches, 'compaction_test' case failed on an x86 server with 1TB memory. And the root cause is that it has too much free memory than what the test supports. @@ Commit message Signed-off-by: Andrew Morton akpm@linux-foundation.org
