Wrong is the wrong word :)
For simple file systems that either don't use block devices, or just
the main one set up by the super.c code using ->put_super is perfectly
fine. Once a file system does something complicated like setting up
their own block devices, or trying to reuse super blocks using custom
rules it basically has to free ->s_fs_info in it's own ->kill_sb
handler. This whole area is a bit messy unfortunately.
