- All sources are built in a single object, reducing namespace pollution. - Kill the ready queue, and handle a busy response to mly_start in callers rather than deferring the command. - Improve our interaction with CAM: - Don't advertise physical channels as SCSI busses by default. - use the SIM queue freeze capability rather than queueing CDBs internally. - force bus reprobe at module load time. - Clean up more resources in mly_free. - Tidy up debugging levels. - Tidy up handling of events (mostly just code cleanliness). - Use explanatory macros for operations on bus/target/channel numbers.
