The GET_EVENT_STATUS_NOTIFICATION ATAPI command is listed as a
mandatory command in the spec but we don't really implement it any of
its sub-commands.
The commit message for the last commit explains why implementing just
the media subcommand is helpful and how it goes a long way in getting
guests to behave as expected.
The difference from the RFC series sent earlier is:
- Split into more patches
- Add tray open/close notification (from Markus)
There certainly is much more work to be done for the other commands
and also for state change handling (tray open / close / new media)
overall for the block layer, but this is a good first step in being
spec-compliant and at the same time making guests work.
Please apply!
