By giving each BDI a \u0027fair\u0027 share of the dirty limit, each one can have\ndirty pages outstanding and make progress.\n\nA global threshold also creates a deadlock for stacked BDIs; when A writes to\nB, and A generates enough dirty pages to get throttled, B will never start\nwriteback until the dirty pages go away. Again, by giving each BDI its own\n\u0027independent\u0027 dirty limit, this problem is avoided.\n\nSo the problem is to determine how to distribute the total dirty limit across\nthe BDIs fairly and efficiently. A DBI that has a large dirty limit but does\nnot have any dirty pages outstanding is a waste.\n\nWhat is done is to keep a floating proportion between the DBIs based on\nwriteback completions. This way faster/more active devices get a larger share\nthan slower/idle devices.\n\n[akpm@linux-foundation.org: fix warnings]\n[hugh@veritas.com: Fix occasional hang when a task couldn\u0027t get out of balance_dirty_pages]\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b2e8fb6efa209c82203c79b491b5bc952d44aa57", "tree": "e4c82e3f2c70a188ced7126435bf153f5f6c4a1c", "parents": [ "e0bf68ddec4f4f90e5871404be4f1854c17f3120" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Tue Oct 16 23:25:47 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed Oct 17 08:42:45 2007 -0700" }, "message": "mm: scalable bdi statistics counters\n\nProvide scalable per backing_dev_info statistics counters.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c4dc4beed23827e155d7cbc2a1ffa3949eddd194", "tree": "b7f115c159fe26b90b7e5b7d5dcf2f9318b69bf1", "parents": [ "1f7d6668c29b1dfa307a44844f9bb38356fc989b" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Tue Oct 16 23:25:41 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed Oct 17 08:42:44 2007 -0700" }, "message": "nfs: remove congestion_end()\n\nThese patches aim to improve balance_dirty_pages() and directly address three\nissues:\n 1) inter device starvation\n 2) stacked device deadlocks\n 3) inter process starvation\n\n1 and 2 are a direct result from removing the global dirty limit and using\nper device dirty limits.
