Reading this again you probably asked why put_filesystem() is exported.

As I see it, that should be called after being done with the return value of
get_fs_type(). Not that it does anything for the always built-in ramfs.
The alternatives I see are a commented-out variant with an explanation or
making put_filesystem() into an inline function.
