Tejun Heo ca23509fba [PATCH] blk: fix dangling pointer access in __elv_add_request ... cfq's add_req_fn callback may invoke q->request_fn directly and depending on low-level driver used and timing, a queued request may be finished & deallocated before add_req_fn callback returns. So, __elv_add_request must not access rq after it's passed to add_req_fn callback. This patch moves rq_mergeable test above add_req_fn(). This may result in q->last_merge pointing to REQ_NOMERGE request if add_req_fn callback sets it but as RQ_NOMERGE is checked again when blk layer actually tries to merge requests, this does not cause any problem.
