Modified files:
sys/ufs/ffs ffs_alloc.c ffs_balloc.c ffs_extern.h
ffs_inode.c ffs_snapshot.c ffs_softdep.c
Log:
When taking a snapshot, we must check for active files that have
been unlinked (e.g., with a zero link count). We have to expunge
all trace of these files from the snapshot so that they are neither
reclaimed prematurely by fsck nor saved unnecessarily by dump.
