-/// `statx(dirfd, path, flags, mask, statxbuf)`
-///
-/// This function returns [`io::Errno::NOSYS`] if `statx` is not available on
-/// the platform, such as Linux before 4.11. This also includes older Docker
-/// versions where the actual syscall fails with different error codes; rustix
-/// handles this and translates them into `NOSYS`.
-///
-/// # References
-///  - [Linux]
-///
-/// # Examples
-///
-/// ```
-/// # use std::path::Path;
-/// # use std::io;
-/// # use rustix::fs::{AtFlags, StatxFlags};
-/// # use rustix::fd::BorrowedFd;
-/// /// Try to determine if the provided path is a mount root. Will return
-/// /// `Ok(None)` if the kernel is not new enough to support `statx` or
-/// /// [`libc::STATX_ATTR_MOUNT_ROOT`].
-/// fn is_mountpoint(root: BorrowedFd<'_>, path: &Path) -> io::Result<Option<bool>> {
-///     use rustix::fs::{AtFlags, StatxFlags};

-///     let mountroot_flag = libc::STATX_ATTR_MOUNT_ROOT as u64;
-///     match rustix::fs::statx(

-///         StatxFlags::empty(),

-///         Ok(r) => {
-///             let present = (r.stx_attributes_mask & mountroot_flag) > 0;
-///             Ok(present.then(|| r.stx_attributes & mountroot_flag > 0))
