Pull MD fixes from Song:
"This set fixes two issues:
1. dmraid regression since 6.7 kernels. This issue was initially
reported in [1]. This set of fix has been reviewed and tested by
md and dm folks.
2. raid5 hang since 6.7 kernel, reported in [2]. We haven't got a
better fix for this issue yet. This revert is a workaround. It has
been applied to 6.7 stable kernels [3], and proved to be affective.
We will look more into this issue for a better 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.
