It has been noted that lumpy reclaim is far too aggressive\nand trashes the system somewhat. As SLUB uses high-order allocations, a\nlarge cost incurred by lumpy reclaim will be noticeable. It was also\nreported during transparent hugepage support testing that lumpy reclaim\nwas trashing the system and these patches should mitigate that problem\nwithout disabling lumpy reclaim.\n\nPatch 7 adds wait_iff_congested() and replaces some callers of\ncongestion_wait(). wait_iff_congested() only sleeps if there is a BDI\nthat is currently congested.

Currently there is no\nway to inspect dirty and writeback speed over time. It\u0027s not possible for\nnr_dirty/nr_writeback.\n\nThese entries are necessary to give visibility into writeback behaviour.\nWe have /proc/diskstats which lets us understand the io in the block\nlayer. We have blktrace for more in depth understanding. We have\ne2fsprogs and debugsfs to give insight into the file systems behaviour,\nbut we don\u0027t offer our users the ability understand what writeback is\ndoing. There is no way to know how active it is over the whole system, if\nit\u0027s falling behind or to quantify it\u0027s efforts. With these values\nexported users can easily see how much data applications are sending\nthrough writeback and also at what rates writeback is processing this\ndata. Comparing the rates of change between the two allow developers to\nsee when writeback is not able to keep up with incoming traffic and the\nrate of dirty memory being sent to the IO back end. This allows folks to\nunderstand their io workloads and track kernel issues. Non kernel\nengineers at Google often use these counters to solve puzzling performance\nproblems.\n\nPatch #4 adds a pernode vmstat file with nr_dirtied and nr_written\n\nPatch #5 add writeback thresholds to /proc/vmstat\n\nCurrently these values are in debugfs. But they should be promoted to\n/proc since they are useful for developers who are writing databases\nand file servers and are not debugging the kernel.\n\nThe output is as below:\n\n # grep threshold /proc/vmstat\n nr_pages_dirty_threshold 409111\n nr_pages_dirty_background_threshold 818223\n\nThis patch:\n\nThis allows code outside of the mm core to safely manipulate page\nwriteback state and not worry about the other accounting.

Instead, we defer the refcount checks to\nreclaim-time and use a per-inode state flag, I_REFERENCED, to tell\nreclaim that iget has touched the inode in the past. This means that\nonly reclaim should be touching the LRU with any frequency, hence\nsignificantly reducing lock acquisitions and the amount contention\non LRU updates.\n\nThis also removes the inode_in_use list, which means we now only\nhave one list for tracking the inode LRU status. This makes it much\nsimpler to split out the LRU list operations under it\u0027s own lock.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nReviewed-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "cffbc8aa334f55c9ed42d25202eb3ebf3a97c195", "tree": "dab046695754e2cec1a7ab7a64b236e976d94360", "parents": [ "be1a16a0ae29a7c90081a657b64aa51cb1a65a27" ], "author": { "name": "Dave Chinner", "email": "dchinner@redhat.com", "time": "Sat Oct 23 05:03:02 2010 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Mon Oct 25 21:26:09 2010 -0400" }, "message": "fs: Convert nr_inodes and nr_unused to per-cpu counters\n\nThe number of inodes allocated does not need to be tied to the\naddition or removal of an inode to/from a list.
