  "message": "mm: bdi: allow setting a minimum for the bdi dirty limit\n\nUnder normal circumstances each device is given a part of the total write-back\ncache that relates to its current avg writeout speed in relation to the other\ndevices.\n\nmin_ratio - allows one to assign a minimum portion of the write-back cache to\na particular device.  This is useful in situations where you might want to\nprovide a minimum QoS.  (One request for this feature came from flash based\nstorage people who wanted to avoid writing out at all costs - they of course\nneeded some pdflush hacks as well)\n\nmax_ratio - allows one to assign a maximum portion of the dirty limit to a\nparticular device.  This is useful in situations where you want to avoid one\ndevice taking all or most of the write-back cache.  Eg.  an NFS mount that is\nprone to get stuck, or a FUSE mount which you don\u0027t trust to play fair.\n\nAdd \"min_ratio\" to /sys/class/bdi.  This indicates the minimum percentage of\nthe global dirty threshold allocated to this bdi.\n\n[mszeredi@suse.cz]\n\n - fix parsing in min_ratio_store()\n - document new sysfs attribute\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
