Merge tag 'io_uring-bio-cache.5-2021-08-30' of git://git.kernel.dk/linux-block
Pull support for struct bio recycling from Jens Axboe: "This adds bio recycling support for polled IO, allowing quick reuse of a bio for high IOPS scenarios via a percpu bio_set list. It's good for almost a 10% improvement in performance, bumping our per-core IO limit from ~3.2M IOPS to ~3.5M IOPS" * tag 'io_uring-bio-cache.5-2021-08-30' of git://git.kernel.dk/linux-block: bio: improve kerneldoc documentation for bio_alloc_kiocb() block: provide bio_clear_hipri() helper block: use the percpu bio cache in __blkdev_direct_IO io_uring: enable use of bio alloc cache block: clear BIO_PERCPU_CACHE flag if polling isn't supported bio: add allocation cache abstraction fs: add kiocb alloc cache flag bio: optimize initialization of a bio
