I would have said that the situation would look less messy if similar flags were set at the same bit. Having 64-bit flags seems to allow it. Hmm...

/usr/include/linux/fcntl.h:#define AT_SYMLINK_NOFOLLOW	0x100   /* Do not follow symbolic links.  */
/usr/include/asm-generic/fcntl.h:#define O_NOFOLLOW	00400000	/* don't follow links */
/usr/include/x86_64-linux-gnu/bits/fcntl-linux.h:# define AT_SYMLINK_NOFOLLOW	0x100	/* Do not follow symbolic links.  */
/usr/include/x86_64-linux-gnu/sys/mount.h:  UMOUNT_NOFOLLOW = 8		/* Don't follow symlink on umount.  */

If they weren't done that way from the start, then that's an ABI change, which isn't allowed.
