We need to commit dirty metadata and pages to disk before remounting exfat as read-only. This fixes a failure in xfstests generic/452 generic/452 does the following: cp something <exfat>/ mount -o remount,ro <exfat> the <exfat>/something is corrupted. because while exfat is remounted as read-only, exfat doesn't have a chance to commit metadata and vfs invalidates page caches in a block device.

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.
