io_uring: define and set show_fdinfo only if procfs is enabled
Follow the pattern used with other *_show_fdinfo functions and only define and use io_uring_show_fdinfo and its helper functions if CONFIG_PROC_FS is set. Fixes: 87ce955b24c9 ("io_uring: add ->show_fdinfo() for the io_uring file descriptor") Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: Jens Axboe <axboe@kernel.dk>
