In the 3.2 version xfs_sync_flags does a double unlock of the ilock - change the last argument of xfs_trans_ijoin from XFS_ILOCK_EXCL to 0 will fix this. The 3.0 version doesn't have this bug. And btw, the additions to the on-disk format are gross - this stuff broke before and will break again when we add new features. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
