Due to the unfreeable\npages, compaction fails.\n\nNeedless to say, at that point page reclaim also fails to create free\ncontiguous 2MB areas. However, that doesn\u0027t stop the current code from\ntrying, over and over again, and freeing a minimum of 4MB (2UL \u003c\u003c\nsc-\u003eorder pages) at every single invocation.\n\nThis resulted in my 12GB system having 2-3GB free memory, a corresponding\namount of used swap and very sluggish response times.\n\nThis can be avoided by having the direct reclaim code not reclaim from\nzones that already have plenty of free memory available for compaction.\n\nIf compaction still fails due to unmovable memory, doing additional\nreclaim will only hurt the system, not help.\n\n[jweiner@redhat.com: change comment to explain the order check]\nSigned-off-by: Rik van Riel \u003criel@redhat.com\u003e\nAcked-by: Johannes Weiner \u003cjweiner@redhat.com\u003e\nAcked-by: Mel Gorman \u003cmgorman@suse.de\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nReviewed-by: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nSigned-off-by: Johannes Weiner \u003cjweiner@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "21ee9f398be209ccbb62929d35961ca1ed48eec3", "tree": "4127e14f4a07a2cb7bc6eb902e9c7b0baab8e84f", "parents": [ "2f1da6421570d064a94e17190a4955c2df99794d" ], "author": { "name": "Minchan Kim", "email": "minchan.kim@gmail.com", "time": "Mon Oct 31 17:09:28 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Oct 31 17:30:50 2011 -0700" }, "message": "vmscan: add barrier to prevent evictable page in unevictable list\n\nWhen a race between putback_lru_page() and shmem_lock with lock\u003d0 happens,\nprogrom execution order is as follows, but clear_bit in processor #1 could\nbe reordered right before spin_unlock of processor #1.
