Jilles Tjoelker 6d6a91c50f nullfs: Improve f_flags in statfs(). ... Include some flags of the nullfs mount itself: MNT_RDONLY, MNT_NOEXEC, MNT_NOSUID, MNT_UNION, MNT_NOSYMFOLLOW. This allows userland code calling statfs() or fstatfs() to see these flags. In particular, this allows opendir() to detect that a -t nullfs -o union mount needs deduplication (otherwise at least . and .. are returned twice) and allows rtld to detect a -t nullfs -o noexec mount as noexec. Turn off the MNT_ROOTFS flag from the underlying filesystem because the nullfs mount is definitely not the root filesystem. Reviewed by: kib MFC after: 1 week		2013-03-02 12:42:23 +00:00
