Thanks for looking at this.
I have applied your patch and I'm still re-running check in lowmem. It takes about 24H so I'll
post the full results when it's done.

Ok, here is the output of the check with btrfs-progs freshly synced from
git, including Lu's just added patch.

Obviously while I'm happy to give further debug info on why my filesystem is in that state and
while check --repair sees nothing to repair, suggestions on how to clean those warnings up, unless they are not going to affect filesystem operation, would be greatly appreciated :)

Thanks,
Marc

Thanks for the updated information. I'm sorry that the false alert make you feel nervous.

However, this looks like another problem. Could you dump this file tree by the following command?
# btrfs-debug-tree -t 3862 <dev> | grep -C 10 18170706
