  Replace the the buffer cache's B_READ, B_WRITE, B_FORMAT, and B_FREEBUF
  b_flags with a separate b_cmd field.  Use b_cmd to test for I/O completion
  as well (getting rid of B_DONE in the process).  This further simplifies
  the setup required to issue a buffer cache I/O.


the B_READ and B_WRITEW flags are mentioned in physio.9. I'm not sure what to put there now. In fact, I'm not even sure how much of physio.9 (and some other manual pages in man9) still applies at all.
