Since 5.4 (5.3.xy was fine) I do get every few days:
# df -h /home/tinderbox/img1

This is a hardened Gentoo linux acting as a QA build bot for their packages:
# uname -a
Linux mr-fox 5.4.2 #2 SMP Thu Dec 5 01:18:19 CET 2019 x86_64 Intel(R) Xeon(R) CPU E5-1650 v3 @ 3.50GHz GenuineIntel GNU/Linux
I do appreciate hints to overcome this situation.

Hi,
Yes this is being discussed in two other threads:
"df shows no available space in 5.4.1"
"100% disk usage reported by "df", 60% disk usage reported by "btrfs
fi usage" - this breaks userspace behaviour"
Seems pretty clear there is a bug, it just needs to be located and fixed.

I checked the git log of the stable kernel v5.4..v5.4.7 but it seems this issue is not yet addressed in the stable tree, or?
