We can't use the standard fs_holder_ops because they're meant for single device filesystems - fs_bdev_mark_dead() in particular - and they assume that the blk_holder is the super_block, which also doesn't work for a multi device filesystem. These generally follow the standard fs_holder_ops; the locking/refcounting is a bit simplified because c->ro_ref suffices, and bch2_fs_bdev_mark_dead() is not necessarily shutting down the entire filesystem.

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 reStructuredText 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.
