fs_mark_dead currently uses get_super to find the superblock for the block device that is going away. This means it is limited to the main device stored in sb->s_dev, leading to a lot of code duplication for file systems that can use multiple block devices. Now that the holder for all block devices used by file systems is set to the super_block, we can instead look at that holder and then check if the file system is born and active, so do that instead.

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.
