i was just wondering if anyone is currently working on implementing
this, or if i should just jump right in. :)  for those who are unfamiliar,
soft updates are a way of ordering metadata writes that increase speed,
and also recovery time.  according to the paper, the speed is very close to
that of unordered writes (within 2% usually).  they also insure that the
on-disk state is consistent to the point where the filesystem can be mounted
rw within seconds, and do the checking in the background.  if anyone is
interested, there is info in the following paper.  well i must go..

later,
chris
