[mszeredi@suse.cz] - fix parsing in max_ratio_store(). - export bdi_set_max_ratio() to modules - limit bdi_dirty with bdi->max_ratio - document new sysfs attribute Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> | ||||
| * | lib: floating proportions | Peter Zijlstra | 2007-10-17 | 1 | -0/+119 |
| Given a set of objects, floating proportions aims to efficiently give the proportional 'activity' of a single item as compared to the whole set. Where 'activity' is a measure of a temporal property of the items. It is efficient in that it need not inspect any other items of the set in order to provide the answer. It is not even needed to know how many other items there are. It has one parameter, and that is the period of 'time' over which the 'activity' is measured.
