Comment # 2 on bug 905832 from David Sterba

I wonder what's wrong here, the GA release is 3.16.6 + about 30 already
backported patches from 3.17 (but not all of them). The 3.16.7 release has a
few btrfs patches but none of them looks related. There are some candidates in
the 3.17.x branches, I'll have a closer look.
