Description

We don't have much in the way of a feedback channel from the kernel, but we could at least point users to dmesg. We could also check to see whether an ENOENT from the kernel is accurate or just due to missing features by looking up the image with librbd.

So, ENOENT successfully confused me a bit, the correct errno returned is ENXIO. kernel returns ENOENT correctly on a missing image or snap.
