- Drivers/transports that want to send a synchronous REQUEST_SENSE command as part of their .queuecommand sequence, have 2 new API's that facilitate in doing so and abstract them from scsi-ml internals. void scsi_eh_prep_cmnd(struct scsi_cmnd *scmd, struct scsi_eh_save *sesci, unsigned char *cmnd, int cmnd_size, int sense_bytes) Will hijack a command and prepare it for request sense if needed. And will save any later needed info into a scsi_eh_save structure. void scsi_eh_restore_cmnd(struct scsi_cmnd* scmd, struct scsi_eh_save *sesci); Will undo any changes done to a command by above function. Making it ready for completion. - Re-factor scsi_send_eh_cmnd() to use above APIs Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
