[ Upstream commit 0b2355fe91ac3756a9e29c8b833ba33f9affb520 ]
For non-static function declarations, external linkage is implied and
the 'extern' keyword isn't needed. Some static checkers complain about
the overuse of 'extern', so clean up all the function declarations.
In addition, remove 'extern' from the definition of
free_local_statfs_inodes(); it isn't needed there, either.
