I don't think you tracked the problem down to the correct commit. The previous commit: 055388a xfs: dynamic speculative EOF preallocation Is the one with the known bug that causes excessive preallocation when files are zero sized. The candidate fix is here: http://oss.sgi.com/archives/xfs/2011-01/msg00281.html Can you see if that solves your problem?
