Running rsync on a debian jessie system with 32GB of RAM and a big
250TB btrfs filesystem. 30 GB of ram show up as cached, not much else
running on the system. Lots of page alloction stalls in dmesg before
hand, and several OOM's after this one as well until it finally killed
the rsync. So more traces available if desired. Started with the 4.7
series kernels, thought it was going to be fixed in 4.9:
