io_uring: define and set show_fdinfo only if procfs is enabled (bebdb65e) · Commits · 戴 / test

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: ("io_uring: add ->show_fdinfo() for the io_uring file descriptor") Signed-off-by:
