Hello Christoph and Hannes,
How about passing a struct scsi_device pointer to the eh_*_reset_handler
callbacks instead of a struct scsi_cmnd pointer? Most SCSI LLD
eh_*_reset_handler implementations don't do anything with the information
passed through the struct scsi_cmnd pointer except reading the SCSI device
pointer and logging the SCSI command CDB. Hannes, is this the same as your
proposal? Do you want to work on this or do you perhaps expect me to prepare
patches to implement that change?
Bart.
