Shaohua Li b2387ddcce blk-mq: fix FUA request hang ... When a FUA request enters its DATA stage of flush pipeline, the request is added to mq requeue list, the request will then be added to ctx->rq_list. blk_mq_attempt_merge() might merge the request with a bio. Later when the request is finished the flush pipeline, the request->__data_len is 0. Then I only saw the bio gets endio called, the original request never finish. Adding REQ_FLUSH_SEQ into REQ_NOMERGE_FLAGS looks an easy fix. stable: 3.15+ Signed-off-by: Shaohua Li <shli@fb.com> Signed-off-by: Jens Axboe <axboe@fb.com>		2015-05-04 13:09:55 -06:00
