函数名称:Some commands like WRITE SAME have a payload or data transfer size which* is different from the size of the request. Any driver that supports such* commands using the RQF_SPECIAL_PAYLOAD flag needs to use this helper to* calculate the data transfer size.
函数原型:static inline unsigned int blk_rq_payload_bytes(struct request *rq)
返回类型:unsigned int
参数:
类型 | 参数 | 名称 |
---|---|---|
struct request * | rq |
974 | 如果rq_flags按位与Look at ->special_vec for the actual data payload instead of thebio chain. 则返回:bv_len |
976 | 返回:blk_rq_bytes(rq) |
