| H A D | blk-mq.h | diff 8cf7961dab42c9177a556b719c15f5b9449c24d1 Sat Apr 25 02:53:36 CDT 2020 Christoph Hellwig <hch@lst.de> block: bypass ->make_request_fn for blk-mq drivers
Call blk_mq_make_request when no ->make_request_fn is set. This is
safe now that blk_alloc_queue always sets up the pointer for make_request
based drivers. This avoids an indirect call in the blk-mq driver I/O
fast path, which is rather expensive due to spectre mitigations.
