I got this kernel warning overnight. Possibly during or after a dedup
using duperemove. I'm not sure if that is relevent. Seems to relate to
fs/btrfs/backref.c line 1266.
Don't know if it is important. Thought I'd post it just in case.
I'm afraid this is a screen-shot in the old fashioned sense:

You are hitting a warning that was removed in : c8195a7b1ad5 ("btrfs:
remove spurious WARN_ON(ref->count < 0) in find_parent_nodes")
In short - you can disregard it. However, it's likely you will continue
seeing it in the future unless you update to 4.16 (the commit is not
tagged for stable ))

Thank you, much appreciated. I think I can manage to wait for 4.16!
