Subject: [PATCH 00 of 11] Use a reader-writer lock for the p2m
Date: Thu, 10 May 2012 15:59:44 +0100 [thread overview]
Message-ID: <patchbomb.1336661984@whitby.uk.xensource.com> (raw)
This is a cleaned-up version of my patch of two weeks ago to make the
p2m lock into an rwlock, with some updates from Andres folded in.
With these applied, p2m lookups are no longer serialized in the
common case (where there are few updates).
I hope to check these in next week, before we branch for 4.2.
