  Branch:      sys/sys   SCSI
  Modified:    sys/sys   buf.h
  Log:
  Add B_ORDERED buffer flag and prototype for the bowrite function.
  
  Bowrite guarantees that buffers queued after a call to bowrite will
  be written after the specified buffer (to a particular device).
  Bowrite does this either by taking advantage of hardware ordering support
  (e.g. tagged queueing on SCSI devices) or by resorting to a synchronous write.

  Branch:      sys/ufs/ufs  SCSI
  Modified:    sys/ufs/ufs  ufs_lookup.c
  Log:
  Use bowrite instead of VOP_BWRITE in a few cases. This can probably be taken
  further.
