The internal freeze mechanism in bcachefs mostly reuses the generic rw<->ro transition code. If the fs happens to shutdown during or after freeze, a transition back to rw can fail. This is expected, but returning an error from the unfreeze callout prevents the filesystem from being unfrozen. Skip the read write transition if the fs is shutdown. This allows the fs to unfreeze at the vfs level so writes will no longer block, but will still fail due to the emergency read-only state of the fs.

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.
