Re: ffs snapshots patch

With your last changes, things are much better now:
/usr/bin/time fssconfig fss0 /home /home/snaps/snap0
      149.85 real         0.00 user         1.16 sys
/home: suspended 0.040 sec, redo 0 of 2556
/usr/bin/time fssconfig fss1 /home /home/snaps/snap1
      227.49 real         0.00 user         1.90 sys
/home: suspended 0.040 sec, redo 0 of 2556
/usr/bin/time fssconfig fss2 /home /home/snaps/snap2
      263.58 real         0.00 user         2.97 sys
/home: suspended 0.040 sec, redo 0 of 2556
/usr/bin/time fssconfig fss3 /home /home/snaps/snap3
      353.23 real         0.00 user         3.88 sys
/home: suspended 0.040 sec, redo 0 of 2556

Taking a snapshot will still probably require a lot of time on
large filesystems with a dozen snapshots, but at last the server
won't hang for a long time.
thanks !
