fs: export empty_aops
With the ->sync_page() hook gone, we have a few users that add their own static address_space_operations without any functions defined. fs/inode.c already has an empty_aops that it uses for init purposes. Lets export that and use it in the places where an otherwise empty aops was defined. Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
