./io_uring -d32 -s32 -c32 -b512 -p1 /dev/nullb0 ~3.3 MIOPS vs 3.5 MIOPS, so gives around extra ~4-5%.
The main part is caching struct block_device + some inlining.
v2: without applied patches, merge previous 6/6 into the second patch get rid of helpers (Jens, Christoph) kill bdev_inode and move inode into bdev (Christoph)
Pavel Begunkov (3): block: cache bdev in struct file for raw bdev IO block: don't hide inode from block_device users blk-mq: optimise *end_request non-stat path
