Subject: [PATCH 0/2] Fix a couple of random hangs.
Date: Sun, 15 Mar 2009 22:40:41 +1100 [thread overview]
Message-ID: <1237117243-25940-1-git-send-email-david@fromorbit.com> (raw)
The first patch fixes a low memory hang where I/O completion
processing triggers memory reclaim which hangs waiting for
I/O completion. The trigger is unwritten extent conversion
blocking completion of normal writes.
The second fixes a log hang which results from excessive load;
we update the push target after we go to sleep so if we are
unlucky enough not to have a current push target far enough
advanced we'll hang.
