nit: we zero the scsi_cmnd payload in scsi_alloc_request() ->
scsi_initialize_rq(), so don't really need the bitwise OR. However it
may be better to keep for change of scsi_initialize_rq() changing in
terms of init.
Hi John,
Thanks for the review.
If scmd->flags would be initialized to a non-zero value in the future
then it would be non-trivial to remember that the above assignment would
have to be changed into a logical or. So I'd like to keep the logical or.

nit: scsi_cmnd.flags is an int, so prob should keep the same type
How about changing the type of scsi_cmnd.flags from 'int' into 'unsigned
int'? I can't think of any reason to make a flags variable signed
instead of unsigned.
Thanks,
Bart.
