Subject: [patch 0/6] mm: optimisations and page ref simplifications
Date: Thu, 19 Jan 2006 20:22:42 +0100 (CET)	[thread overview]
Message-ID: <20060119192131.11913.27564.sendpatchset@linux.site> (raw)

In the following patchset (against 2.6.16-rc1-git2), patches 1-4 reduce
the number of locks and atomic operations required in some critical page
manipulation paths.

Patches 5 and 6 help simplify some tricky race avoidance code at the
cost of possibly a very minor performance hit in page reclaim on some
architectures. If they need any more justification they will be needed
for lockless pagecache.

Do these look OK?

Thanks,
Nick
