BTRFS: bdev /dev/mapper/dshelf1 errs: wr 2970, rd 848, flush 0, corrupt 189, gen 0

[Marc MERLIN <marc@merlins.org>]

So, I had an FS with a few issues, I ran btrfs check --repair to completion

Then, after mounting, I still get this warning.
Shouldn't those error counters be reset after check --repair?

Kernel: 4.2.5
Btrfs-tools: 4.3-1

If that matters, here's the output of check --repair (captured with script
-f, so the output is a bit wrong):
