Name:blk_complete_sghdr_rq
Proto:static int blk_complete_sghdr_rq(struct request *rq, struct sg_io_hdr *hdr, struct bio *bio)
Type:int
Parameter:
Type | Parameter | Name |
---|---|---|
struct request * | rq | |
struct sg_io_hdr * | hdr | |
struct bio * | bio |
248 | ret = 0 |
253 | [o] scsi status = result & 0xff |
258 | [o] auxiliary information = 0 |
259 | If [o] shifted, masked scsi status || [o] errors from host adapter || [o] errors from software driver Then [o] auxiliary information |= something abnormal happened |
264 | If sense_len && [i], [*o] points to sense_buffer memory Then |
265 | len = min - return minimum of two values of the same or compatible types*@x: first value*@y: second value((unsignedint) [i] max length to write to sbp , sense_len) |
267 | If Not copy_to_user( [i], [*o] points to sense_buffer memory , sense, len) Then [o] byte count actually written to sbp = len |
277 | Return ret |
