The first two patches are the AIO/DIO vs unwritten extent conversion fixes already sent out before. The first patch will go in through both the XFS and ext4 tree, so it needs to be applied as-is to not cause any problems. The last patch optimized the I/O completion handling for direct I/O. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
