From: Keith Busch <kbusch@xxxxxxxxxx> This value is used for merging considerations, so it needs to be accurate. Reviewed-by: Christoph Hellwig <hch@xxxxxx> Signed-off-by: Keith Busch <kbusch@xxxxxxxxxx> --- v3->v4: Removed the "#if defined" condition. Replaced the 'bi_opf & REQ_INTEGRITY' check with bio_integrity(). If CONFIG_BLK_DEV_INTEGRITY is not set, the stub function will return NULL inline, so the compiler will optimize the setting without adding runtime overhead. block/blk-mq.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/block/blk-mq.c b/block/blk-mq.c index ef3a2ed499563..82219f0e9a256 100644 --- a/block/blk-mq.c +++ b/block/blk-mq.c @@ -2544,6 +2544,9 @@ static void blk_mq_bio_to_request(struct request *rq, struct bio *bio, rq->__sector = bio->bi_iter.bi_sector; rq->write_hint = bio->bi_write_hint; blk_rq_bio_prep(rq, bio, nr_segs); + if (bio_integrity(bio)) + rq->nr_integrity_segments = blk_rq_count_integrity_sg(rq->q, + bio); /* This can't fail, since GFP_NOIO includes __GFP_DIRECT_RECLAIM. */ err = blk_crypto_rq_bio_prep(rq, bio, GFP_NOIO); -- 2.43.5
