block: fix timeout changes for legacy request drivers
blk_mq_complete_request can only be called for blk-mq drivers, but when removing the BLK_EH_HANDLED return value, two legacy request timeout methods incorrectly got switched to call blk_mq_complete_request. Call __blk_complete_request instead to reinstance the previous behavior. For that __blk_complete_request needs to be exported. Fixes: 1fc2b62e ("scsi_transport_fc: complete requests from ->timeout") Fixes: 0df0bb08 ("null_blk: complete requests from ->timeout") Reported-by: Jianchao Wang <jianchao.w.wang@oracle.com> Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
