Well, I also thought about this. But I again did not want to invent
anything complex because main file systems - ext4, btrfs, xfs - do not
use 'write_super()' at all.

Sorry, ext4 does use it in the non-journal mode but I have patches which
kill it, although not looked at by Ted so far.

 And then only these dying / rare
file-systems like btrfs / hfs - I did not feel like over-engineering
is
needed.

Sorry, of course I meant reiserfs, not btrfs.

So what's left is hfs/hfsplus, affs, ufs, udf, reiserfs, jffs2. I could
optimize them if needed, but is this worth the effort?
