    sys/kern             vfs_bio.c 
  Add regetblk() - reacquire a buffer lock.  The buffer must be B_LOCKED or
  must be interlocked with bio_ops.  Used by HAMMER.
  Further changes to B_LOCKED buffers.  A B_LOCKED|B_DELWRI buffer will be
  placed on the dirty queue and then returned to the locked queue once the
  I/O completes.  That is, B_LOCKED does not interfere with B_DELWRI
