1/ fix bug where cd0a was unusable because it was compared against
the number of 2k blocks not the number of 512byte blocks.. gave
an error for all reads past 1/4 way through the disk (cd0d was ok).
2/ fix open code so that it now notices if a disk has been changed
and updates the disklabel.
3/ use the new error handling code from st.c
4/ start adding stuff to get ready for using cd_scsi_cmd from
cd_start (like is done in st and sd)
5/ more general cleanups including making dmesg report
sector size of disk.. (believe it or not SUN drives use 512 byte)
in your config file from:
device cd0
device cd1
...
device cdn
to either
device cd0
or
psuedo-device cd0
The driver now dynamically allocates all per unit dependent structs, so it
will never run out of units (okay, so now we need 32 bit device major/minor
numbers!). It will allocate unit numbers as it needs them.
data. cd_data is now malloced on a per unit basis.
Protected all if ({scsi,cd}_debug).... with #ifdef CDDEBUG to reduce the
the size of the kernel when not debugging.
