Since the introduction of 'BT_TAG_ITER_STARTED' by commit 602380d28e28 ("blk-mq: add blk_mq_all_tag_iter"), the bt_tags_for_each() is not only used for started request, e.g., in below case: blk_mq_hctx_has_requests() -> blk_mq_all_tag_iter() -> __blk_mq_all_tag_iter() --> only BT_TAG_ITER_STATIC_RQS is set -> bt_tags_for_each() -> bt_tags_iter() Signed-off-by: Dongli Zhang <dongli.zhang@oracle.com> --- block/blk-mq-tag.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-)
