(e.g. ide-scsi doesn't return autosense) In drafts I'm more and more seeing ``targets MUST support and enable autosense.'' If indeed we put a ``MUST'' requirement on SCSI LLDD to support and enable autosense, which will indeed streamline things, then this will save me a an _irq_ spin lock over a simple spin lock... What is the future of this requrement? -- Luben
