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.
