Looking at the code in ffs_mountfs(), this is data pulled straight from
the superblock, so I think its some recordkeeping that softupdates is
doing. Immediately after reading those fields they are zeroed so I think
its information on where softupdates was at when the filesystem (or
snapshot) was mounted. Obviously if there are outstanding softupdate ops
when the snapshot is taken it may not be including those in the snap.
AFAIK its harmless.
