The root cause is that test_bit/set_bit atomic operations are actually implemented in relaxed forms, and uninitialized fields governed by an atomic bit could be observed in advance due to memory reordering thus memory barrier pairs should be used. There is also a trivial fix of crafted blkszbits generated by syzkaller.

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.
