4.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jeff Layton <jeff.layton@xxxxxxxxxxxxxxx>
commit ee296d7c5709440f8abd36b5b65c6b3e388538d9 upstream.
They just call file_inode and then the corresponding *_inode_file_wait
function. Just make them static inlines instead.
