SCSI_NORMALIZE_SENSE(9) SCSI mid layer SCSI_NORMALIZE_SENSE(9)
NAME
scsi_normalize_sense - normalize main elements from either fixed or descriptor sense data format into a common format.
SYNOPSIS
int scsi_normalize_sense(const u8 * sense_buffer, int sb_len, struct scsi_sense_hdr * sshdr);
ARGUMENTS
sense_buffer
byte array containing sense data returned by device
sb_len
number of valid bytes in sense_buffer
sshdr
pointer to instance of structure that common elements are written to.
NOTES
The "main elements" from sense data are: response_code, sense_key, asc, ascq and additional_length (only for descriptor format).
Typically this function can be called after a device has responded to a SCSI command with the CHECK_CONDITION status.
RETURN VALUE
1 if valid sense data information found, else 0;
