    sys/kern             kern_lock.c vfs_bio.c 
    sys/sys              buf.h lockmgr.h 
  Log:
  If the buffer lock has waiters after the buffer has changed identity then
  getnewbuf() needs to drop the buffer in order to wake waiters that might
  sleep on the buffer in the context of the old identity.
