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.
