It reclaims a large number of pages and\nignores the age of the pages it reclaims.

      "message": "writeback: stop background/kupdate works from livelocking other works\n\nBackground writeback is easily livelockable in a loop in wb_writeback() by\na process continuously re-dirtying pages (or continuously appending to a\nfile).  This is in fact intended as the target of background writeback is\nto write dirty pages it can find as long as we are over\ndirty_background_threshold.\n\nBut the above behavior gets inconvenient at times because no other work\nqueued in the flusher thread\u0027s queue gets processed.  In particular, since\ne.g.  sync(1) relies on flusher thread to do all the IO for it, sync(1)\ncan hang forever waiting for flusher thread to do the work.\n\nGenerally, when a flusher thread has some work queued, someone submitted\nthe work to achieve a goal more specific than what background writeback\ndoes.  Moreover by working on the specific work, we also reduce amount of\ndirty pages which is exactly the target of background writeout.  So it\nmakes sense to give specific work a priority over a generic page cleaning.\n\nThus we interrupt background writeback if there is some other work to do.\nWe return to the background writeback after completing all the queued\nwork.\n\nThis may delay the writeback of expired inodes for a while, however the\nexpired inodes will eventually be flushed to disk as long as the other\nworks won\u0027t livelock.\n\n[fengguang.wu@intel.com: update comment]\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: Wu Fengguang \u003cfengguang.wu@intel.com\u003e\nCc: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Dave Chinner \u003cdavid@fromorbit.com\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Jan Engelhardt \u003cjengelh@medozas.de\u003e\nCc: Jens Axboe \u003caxboe@kernel.dk\u003e\n\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "mm: page allocator: adjust the per-cpu counter threshold when memory is low\n\nCommit aa45484 (\"calculate a better estimate of NR_FREE_PAGES when memory\nis low\") noted that watermarks were based on the vmstat NR_FREE_PAGES.  To\navoid synchronization overhead, these counters are maintained on a per-cpu\nbasis and drained both periodically and when a threshold is above a\nthreshold.  On large CPU systems, the difference between the estimate and\nreal value of NR_FREE_PAGES can be very high.  The system can get into a\ncase where pages are allocated far below the min watermark potentially\ncausing livelock issues.  The commit solved the problem by taking a better\nreading of NR_FREE_PAGES when memory was low.\n\nUnfortately, as reported by Shaohua Li this accurate reading can consume a\nlarge amount of CPU time on systems with many sockets due to cache line\nbouncing.  This patch takes a different approach.  For large machines\nwhere counter drift might be unsafe and while kswapd is awake, the per-cpu\nthresholds for the target pgdat are reduced to limit the level of drift to\nwhat should be a safe level.  This incurs a performance penalty in heavy\nmemory pressure by a factor that depends on the workload and the machine\nbut the machine should function correctly without accidentally exhausting\nall memory on a node.  There is an additional cost when kswapd wakes and\nsleeps but the event is not expected to be frequent - in Shaohua\u0027s test\ncase, there was one recorded sleep and wake event at least.\n\nTo ensure that kswapd wakes up, a safe version of zone_watermark_ok() is\nintroduced that takes a more accurate reading of NR_FREE_PAGES when called\nfrom wakeup_kswapd, when deciding whether it is really safe to go back to\nsleep in sleeping_prematurely() and when deciding if a zone is really\nbalanced or not in balance_pgdat().  We are still using an expensive\nfunction but limiting how often it is called.\n\nWhen the test case is reproduced, the time spent in the watermark\nfunctions is reduced.  The following report is on the percentage of time\nspent cumulatively spent in the functions zone_nr_free_pages(),\nzone_watermark_ok(), __zone_watermark_ok(), zone_watermark_ok_safe(),\nzone_page_state_snapshot(), zone_page_state().\n\nvanilla                      11.6615%\ndisable-threshold            0.2584%\n\nDavid said:\n\n: We had to pull aa454840 \"mm: page allocator: calculate a better estimate\n: of NR_FREE_PAGES when memory is low and kswapd is awake\" from 2.6.36\n: internally because tests showed that it would cause the machine to stall\n: as the result of heavy kswapd activity.

      "message": "dm: raid456 basic support\n\nThis patch is the skeleton for the DM target that will be\nthe bridge from DM to MD (initially RAID456 and later RAID1).  It\nprovides a way to use device-mapper interfaces to the MD RAID456\ndrivers.\n\nAs with all device-mapper targets, the nominal public interfaces are the\nconstructor (CTR) tables and the status outputs (both STATUSTYPE_INFO\nand STATUSTYPE_TABLE).  The CTR table looks like the following:\n\n1: \u003cs\u003e \u003cl\u003e raid \\\n2:\t\u003craid_type\u003e \u003c#raid_params\u003e \u003craid_params\u003e \\\n3:\t\u003c#raid_devs\u003e \u003cmeta_dev1\u003e \u003cdev1\u003e .. \u003cmeta_devN\u003e \u003cdevN\u003e\n\nLine 1 contains the standard first three arguments to any device-mapper\ntarget - the start, length, and target type fields.  The target type in\nthis case is \"raid\".\n\nLine 2 contains the arguments that define the particular raid\ntype/personality/level, the required arguments for that raid type, and\nany optional arguments.  Possible raid types include: raid4, raid5_la,\nraid5_ls, raid5_rs, raid6_zr, raid6_nr, and raid6_nc.  (again, raid1 is\nplanned for the future.)  The list of required and optional parameters\nis the same for all the current raid types.  The required parameters are\npositional, while the optional parameters are given as key/value pairs.\nThe possible parameters are as follows:\n \u003cchunk_size\u003e\t\tChunk size in sectors.\n [[no]sync]\t\tForce/Prevent RAID initialization\n [rebuild \u003cidx\u003e]\tRebuild the drive indicated by the index\n [daemon_sleep \u003cms\u003e]\tTime between bitmap daemon work to clear bits\n [min_recovery_rate \u003ckB/sec/disk\u003e]\tThrottle RAID initialization\n [max_recovery_rate \u003ckB/sec/disk\u003e]\tThrottle RAID initialization\n [max_write_behind \u003cvalue\u003e]\t\tSee \u0027-write-behind\u003d\u0027 (man mdadm)\n [stripe_cache \u003csectors\u003e]\t\tStripe cache size for higher RAIDs\n\nLine 3 contains the list of devices that compose the array in\nmetadata/data device pairs.  If the metadata is stored separately, a \u0027-\u0027\nis given for the metadata device position.  If a drive has failed or is\nmissing at creation time, a \u0027-\u0027 can be given for both the metadata and\ndata drives for a given position.\n\nExamples:\n# RAID4 - 4 data drives, 1 parity\n# No metadata devices specified to hold superblock/bitmap info\n# Chunk size of 1MiB\n# (Lines separated for easy reading)\n0 1960893648 raid \\\n\traid4 1 2048 \\\n\t5 - 8:17 - 8:33 - 8:49 - 8:65 - 8:81\n\n# RAID4 - 4 data drives, 1 parity (no metadata devices)\n# Chunk size of 1MiB, force RAID initialization,\n#\tmin recovery rate at 20 kiB/sec/disk\n0 1960893648 raid \\\n        raid4 4 2048 min_recovery_rate 20 sync\\\n        5 - 8:17 - 8:33 - 8:49 - 8:65 - 8:81\n\nPerforming a \u0027dmsetup table\u0027 should display the CTR table used to\nconstruct the mapping (with possible reordering of optional\nparameters).\n\nPerforming a \u0027dmsetup status\u0027 will yield information on the state and\nhealth of the array.  The output is as follows:\n1: \u003cs\u003e \u003cl\u003e raid \\\n2:\t\u003craid_type\u003e \u003c#devices\u003e \u003c1 health char for each dev\u003e \u003cresync_ratio\u003e\n\nLine 1 is standard DM output.  Line 2 is best shown by example:\n\t0 1960893648 raid raid4 5 AAAAA 2/490221568\nHere we can see the RAID type is raid4, there are 5 devices - all of\nwhich are \u0027A\u0027live, and the array is 2/490221568 complete with recovery.\n\nCc: linux-raid@vger.kernel.org\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\nSigned-off-by: Jonathan Brassow \u003cjbrassow@redhat.com\u003e\nSigned-off-by: Mike Snitzer \u003csnitzer@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n"
