Since you can have more nodes in /dev with the same node numbers, and
this actually is useful (for granting more users/groups access to the
devices in question), this is not going to fly.

No, I'm talking about the *other* direction now: I'm looking at a file
in /dev and I want to find the corresponding sysfs device (if any).

Anyway turns out that sysfs dev numbers are not unique either -- some
devices with major=1 apper twice in sysfs. To give a random example:

$ cat /sys/block/ram8/dev /sys/class/mem/random/dev
1:8
1:8

And these aren't symlinks.
