The only changes have been to address the issues that Brain pointed out during review. The patchset has been used in all my testing since the first version was posted, and most of that has been with lockdep enabled. I have not had lockdep trip over anything other than already known issues in xfstests and various stress loads that I've run, so I think this is good to go. Comments, thoughts? -Dave. _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
