Example

let target_dir = "/tmp/nc-umount";
let ret = unsafe { nc::mkdirat(nc::AT_FDCWD, target_dir, 0o755) };
assert!(ret.is_ok());

let src_dir = "/etc";
let fs_type = "";
let mount_flags = nc::MS_BIND | nc::MS_RDONLY;
let data = 0;
let ret = unsafe { nc::mount(src_dir, target_dir, fs_type, mount_flags, data) };
assert!(ret.is_err());
assert_eq!(ret, Err(nc::EPERM));

let ret = unsafe { nc::umount(target_dir) };
assert!(ret.is_err());

let ret = unsafe { nc::unlinkat(nc::AT_FDCWD, target_dir, nc::AT_REMOVEDIR) };
assert!(ret.is_ok());
