Bill,

Here are a few comments on the CAM-3 March 1995 minutes sent
March 23.

What error code should be used if the XPT_WAITOK flag is cleared
to zero and the memory allocation service believes the request
could never be honored with XPT_WAITOK = 0 but that the request
possibly could be honored with XPT_WAITOK = 1?

How are errors indicated?

Again, how are errors indicated?
