By the way:

$ cd linux/fs
$ grep -l FS_REQUIRES_DEV */*.[ch] | sed 's@/.*@@' | sort -u | xargs  
echo
adfs affs befs bfs btrfs cramfs efs ext2 ext3 ext4 f2fs fat freevxfs  
fuse gfs2 hfs hfsplus hpfs isofs jfs logfs minix nfsd nilfs2 ntfs ocfs2  
omfs qnx4 qnx6 reiserfs romfs squashfs sysv udf ufs xfs

That should be all the block backed filesystems in the linux kernel, so  
if we cover all those we're good. (I'm not hugely interested in  
fuse-only filesystems, that could be anything.)

The ones we _don't_ currently have are:
affs befs efs freevxfs fuse gfs2 hfs hfsplus hpfs isofs logfs minix  
nfsd ocfs2 omfs qnx4 qnx6 sysv udf ufs

What's 'xiafs'? It's not in that list. Apparently portions of it are  
used in fs/qnx4...

Removed in the 2.1 development series. Uh-huh. That's more than a  
decade ago now, I think we can yank support for that.
