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. Shem - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
