- Fix a race when we were calling folio_next() in the BIO folio iter
without holding a reference, meaning the folio could be split or freed,
and we'd jump to the next page instead of the intended next folio.
- Fix readahead creating single-page folios instead of the intended
large folios when doing reads that are not a power of two in size.

Pull folio fixes from Matthew Wilcox:
"Two folio fixes for 5.18.
Darrick and Brian have done amazing work debugging the race I created
in the folio BIO iterator. The readahead problem was deterministic, so
easy to fix.

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.
