| H A D | bounce.c | 51d798cd Wed Jul 27 11:22:56 CDT 2022 Christoph Hellwig <hch@lst.de> block: change the blk_queue_bounce calling convention
The double indirect bio leads to somewhat suboptimal code generation.
Instead return the (original or split) bio, and make sure the
request_queue arguments to the lower level helpers is passed after the
bio to avoid constant reshuffling of the argument passing registers.
