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

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
