scsi_eh_prep_cmnd — Save a scsi command info as part of error recovery
void scsi_eh_prep_cmnd ( | struct scsi_cmnd * scmd, |
| struct scsi_eh_save * ses, | |
| unsigned char * cmnd, | |
| int cmnd_size, | |
unsigned sense_bytes); |
struct scsi_cmnd * scmdSCSI command structure to hijack
struct scsi_eh_save * sesstructure to save restore information
unsigned char * cmndCDB to send. Can be NULL if no new cmnd is needed
int cmnd_size
size in bytes of cmnd (must be <= BLK_MAX_CDB)
unsigned sense_bytes
size of sense data to copy. or 0 (if != 0 cmnd is ignored)
This function is used to save a scsi command information before re-execution
as part of the error recovery process. If sense_bytes is 0 the command
sent must be one that does not transfer any data. If sense_bytes != 0
cmnd is ignored and this functions sets up a REQUEST_SENSE command
and cmnd buffers to read sense_bytes into scmd->sense_buffer.
