When an AG is first marked as having reclaimable inodes,\nthe background reclaim work is kicked. It will continue to run\nperiodically untill it detects that there are no more reclaimable\ninodes. It will be kicked again when the first inode is queued for\nreclaim.\n\nTo ensure shrinker based inode reclaim throttles to the inode\ncleaning and reclaim rate but still reclaim inodes efficiently, make it kick the\nbackground inode reclaim so that when we are low on memory we are\ntrying to reclaim inodes as efficiently as possible. This kick shoul\nd not be necessary, but it will protect against failures to kick the\nbackground reclaim when inodes are first dirtied.\n\nTo provide the rate throttling, make the shrinker pass do\nsynchronous inode reclaim so that it blocks on inodes under IO. This\nmeans that the shrinker will reclaim inodes rather than just\nskipping over them, but it does not adversely affect the rate of\nreclaim because most dirty inodes are already under IO due to the\nbackground reclaim work the shrinker kicked.\n\nThese two modifications solve one of the two OOM killer invocations\nChris Mason reported recently when running a stress testing script.\nThe particular workload trigger for the OOM killer invocation is\nwhere there are more threads than CPUs all unlinking files in an\nextremely memory constrained environment.

This simply slows\ndown allocation at ENOSPC.\n\nWe really only need one active flush at a time, and we can easily\nimplement that via the new xfs_syncd_wq. All we need to do is queue\na flush if one is not already active, then block waiting for the\ncurrently active flush to complete. The result is that we only ever\nhave a single ENOSPC inode flush active at a time and this greatly\nreduces the overhead of ENOSPC processing.\n\nOn my 2p test machine, this results in tests exercising ENOSPC\nconditions running significantly faster - 042 halves execution time,\n083 drops from 60s to 5s, etc - while not introducing test\nregressions.\n\nThis allows us to remove the old xfssyncd threads and infrastructure\nas they are no longer used.\n\nSigned-off-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nReviewed-by: Christoph Hellwig \u003chch@lst.de\u003e\nReviewed-by: Alex Elder \u003caelder@sgi.com\u003e\n" }, { "commit": "c6d09b666de11eb272326a6eb6cd3246da571014", "tree": "74951ec04191b47a1fb75f9e79de6c00837a7c17", "parents": [ "e828776a8abe6b9bae7ed9638710bff7642c568a" ], "author": { "name": "Dave Chinner", "email": "dchinner@redhat.com", "time": "Fri Apr 08 12:45:07 2011 +1000" }, "committer": { "name": "Dave Chinner", "email": "david@fromorbit.com", "time": "Fri Apr 08 12:45:07 2011 +1000" }, "message": "xfs: introduce a xfssyncd workqueue\n\nAll of the work xfssyncd does is background functionality.
