loop advertises REQ_NOWAIT support via BLK_FEAT_NOWAIT (set by default for all blk-mq devices), but delegates I/O processing to workqueues where blocking operations are allowed. Since REQ_NOWAIT is not valid in the workqueue context, clear the REQ_NOWAIT flag before handing the request over to the workqueue. This avoids unnecessary non-blocking constraints in a context where blocking is acceptable. Signed-off-by: Chaitanya Kulkarni <ckulkarnilinux@gmail.com>
