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. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
