Comment # 80 on bug 1017461 from Sven Heithecker

Hi, I encountered the same issue (AMD Ryzen, M.2 PCIE SSD, Leap 42.2) with
btrfs as root fs.

The number of snapshots is: 
# btrfs subvolume list -a | wc -l
55

I cannot disable quotas because there is always a rescan operation running:
# btrfs quota rescan -a /
rescan operation running (current key 0)
(The "key" does not change)

"btrfs scrub" showed no errors.

Any ideas how I at least can disable the btrfs quotas ?
