It's just messy as it will require changes in all file systems.

Unless I'm badly misreading the patch the op switch() is fixed in VFS mapping
to clearly defined inode operations. It is not extensible per filesystem.
Arguably they could be split into individual syscalls, but it looks not more 
like cosmetics at this point.
