* The following flags may be specified:
*
* - `MS_RDONLY` (mount read-only)
* - `MS_NOSUID` (don't honor S_ISUID bit)
* - `MS_NODEV` (disallow special files)
* - `MS_NOEXEC` (disallow program execution)
* - `MS_SYNCHRONOUS` (writes are synced at once)
* - `MS_NOATIME` (do not update access times)
* - `MS_REMOUNT` (tune existing mounting)
*
* The following flags may also be used, but could be set to zero at
* runtime if the underlying kernel doesn't support them.
*
* - `MNT_ASYNC` (xnu, freebsd, openbsd, netbsd)
* - `MNT_RELOAD` (xnu, freebsd, openbsd, netbsd)
* - `MS_STRICTATIME` (linux, xnu)
* - `MS_RELATIME` (linux, netbsd)
