Both ->start_time_ns and the RQF_IO_STAT are set when the request is allocated using blk_mq_alloc_request by dm-mpath in blk_mq_rq_ctx_init. The block layer also ensures ->start_time_ns is only set when actually needed. Signed-off-by: Christoph Hellwig <hch@lst.de> --- drivers/md/dm-rq.c | 4 ---- 1 file changed, 4 deletions(-)
