The percpu pageset (pcp) code is looking a little old and neglected these days. This set does a couple of these things (in order of importance, not order of implementation in the series):
1. Change the default pageset pcp->high value from 744kB to 512k. (see "consolidate high-to-batch ratio code") 2. Allow setting of vm.percpu_pagelist_fraction=0, which takes you back to the boot-time behavior 3. Resolve inconsistencies in the way the boot-time and sysctl pcp code works. 4. Clarify some function names and code comments. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
