  Modified files:
    sys/ufs/ffs          ffs_snapshot.c 
  Log:
  Eliminate a deadlock that can occur when a dirty block belonging to a snapshot
  file is flushed by a process not holding snaplk (e.g. bufdaemon).  Another
  process might hold snaplk and try to access the block due to ffs_copyonwrite
  processing.
