This is another try based upon Christoph and Trond's suggestions in the 'wsync
export option' thread. I've added the export operation and combined
nfsd_sync_dir and write_inode_now usage into nfsd_sync2 which passes the buck
onto XFS. It's been very lightly tested. It's just a little bit faster than
the previous try:
# time tar -xvf /mnt2/quilt-0.47.tar > /dev/null
plain jane:
0m13.177s 0m13.301s 0m13.528s
previous try:
0m8.361s 0m8.400s 0m8.301s
w/ xfs commit_metadata op:
0m7.426s 0m7.340s 0m7.198s
Thanks!
