From 07db59bd6b0f279c31044cba6787344f63be87ea Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Fri, 27 Apr 2007 09:10:47 -0700 Subject: [PATCH] Change default dirty-writeback limits Do this really early in the 2.6.22-rc series, so that we'll get feedback. And don't change by half measures. Just cut the default dirty limit to a quarter of what it was, and see if anybody even notices.
