libcam/Makefile: Add scsi_da.c to libcam for the new
scsi_format_unit() function.
camcontrol.8: Update the man page for the new format
functionality, and take out the examples section
describing how to do it with 'camcontrol cmd'.
camcontrol.c: New format functionality. Note that unlike the
rest of the camcontrol subcommands, this one is
interactive by default. Because of the potential
destructiveness of the format command, I thought
it necessary to get confirmation from the user
before spamming a disk. You can disable the
interactive behavior, and the status meter with
command line arguments.
scsi_da.c: Add the new scsi_format_unit() cdb building
function and use #ifdef _KERNEL to make this file
compile in both the kernel and userland. The
format unit function is currently only defined in
the non-kernel case, because nothing in the kernel
is using it. If that changes, it should be
un-ifdefed and compiled in both cases.
scsi_da.h: New function declaration, CDB structure and format
data structures.
Thanks to Nick Hibma for providing some valuable input on these changes.
without the DA driver.
The problem was that the CD driver depended on scsi_read_write() and
scsi_start_stop(), which were defined in scsi_da.c.
I moved both functions, and their associated data structures and defines
from scsi_da.* to scsi_all.*. This is technically the "wrong" thing to do
since those commands are really only for direct-access type devices, not
for all SCSI devices. I think, though, that the advantage (allowing people
to compile kernels without the disk driver) outweighs any architectural
purity arguments.
