Eric Hagberg 42a6aeb4b2 Revert "loop: Avoid updating block size under exclusive owner"
Revert commit ce8da5d13d which is commit
7e49538288e523427beedd26993d446afef1a6fb upstream.

This reverts commit ce8da5d13d ("loop: Avoid updating block size under
exclusive owner") for the 6.6 kernel, because if the LTP ioctl_loop06 test is
run with this patch in place, the test will fail, it leaves the host unable to
kexec into the kernel again (hangs forever) and "losetup -a" will hang on
attempting to access the /dev/loopN device that the test has set up.

The patch doesn't need to be reverted from 6.12, as it works fine there.

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.
