Hi all, This is an attempt to fix a race when queuing a buffer to a delwri queue that happens to already sit on a delwri queue wait list. The problem is reproduced by xfs/305 under particular conditions. The details are described in the commit log description of patch 2. This survives xfstests and repeated runs of xfs/305. Note that the test still reproduces the known log deadlock problem when quotaoff runs against a heavily loaded fs. I've hacked around that problem locally to rule it out from repetition testing of xfs/305. Thoughts, reviews, flames appreciated.
