scsi_eh_prep_cmnd — Save a scsi command info as part of error recory
void scsi_eh_prep_cmnd ( | struct scsi_cmnd * scmd, |
struct scsi_eh_save * ses, | |
unsigned char * cmnd, | |
int cmnd_size, | |
unsigned sense_bytes) ; |
scmd
SCSI command structure to hijack
ses
structure to save restore information
cmnd
CDB to send. Can be NULL if no new cmnd is needed
cmnd_size
size in bytes of cmnd
(must be <= BLK_MAX_CDB)
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.
