The patch
[SCSI] SCSI core kmalloc2kzalloc
Has an incorrect piece in sr_ioctl.c; it changes buffer from kmalloc
to kzalloc, but then removes the clearing of the stack variable struct
packet_command. This, in turn leaves rubbish in the sense pointer
which the sr_do_ioctl() command then happily writes to ... oops.
Thanks to Mike Christie <michaelc@cs.wisc.edu> for spotting this.

Change the core SCSI code to use kzalloc rather than kmalloc+memset
where possible.

split each ioctl handled in sr_audio_ioctl into a function of it's own.
This cleans the code up nicely, and allows various places in sr_ioctl
to call these helpers directly instead of going through the multiplexer.

This follows almost the identical model to sd, except that there's one
ioctl which returns raw sense data, so it had to use scsi_execute()
instead.

I noticed a case in sr_ioctl.c's sr_get_mcn where a buffer is
allocated, but the pointer isn't checked for null.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
