Hello gurus,
I have a lot of questions on scsi error handling and scsi in general.
1. Do we have to provide a scsi_command method() ?
2. Where are the error returns of scsi_queuecommand() defined ?
3. What method should we provide if the only action we can undertake is a
generic reset ?
4. Is there a consensus on how to handle a short transfer ? Can we set the
resid field and report an error ? Will the data be transfered up
nevertheless ?
5. Under which conditions is an error reported to user space ?
6. Is gathering sense data still optional ?
Please, if you are telling me to read the source, tell me which file to
read.
TIA
Oliver
