Subject: [PATCH] fuse: show the io_uring mount option

From: kuangkai <kuangkai@...inos.cn>

mount with io_uring options will not work if the kernel parameter of /sys/module/fuse/parameters/enable_uring has not been set,
displaying this option can help confirm whether the fuse over io_uring function is enabled.
