Add the definition of pvSCSI protocol used between the pvSCSI frontend in a
XEN domU and the pvSCSI backend in a XEN driver domain (usually Dom0).
This header was originally provided by Fujitsu for XEN based on Linux 2.6.18.
Changes are:
- added comment
- adapt to Linux style guide
- add support for larger SG-lists by putting them in an own granted page
- remove stale definitions
This is a protocol extension and needs to be reviewed separately, and
the Xen header needs updating as well.
Sure. The review can start right now. Updating the Xen header will be
done as soon as the drivers are accepted in Linux.
The documentation for this protocol is rather lacking. In particular it
is missing the connection states.
Regarding documentation: I'll add some.
Regarding the connection states: I'd rather move the description in
blkif.h to xenbus.h than duplicating it in vscsiif.h. What do you think?
