Comment # 10 on bug 1111414 from Arvin Schnell

I had the chance to look at the issue now.

First thing to notice is that SLE15 is also affected while SLE12 SP4 is not
affected.

AFAIS the change leading to the problem is in libbtrfs (4.11), but not even the
patchlevel of libbtrfs was increased. On the other hand the patch for snapper
should also work with the older libbtrfs.

David, can you please confirm this?
