Subject: linux 4.7.2 & btrfs & rsync & OOM gone crazy

Just upgraded from 4.6.5 to 4.7.2 for my btrfs backup server with 32GB of
ram. Only thing that run's on it is an rsync of an NFS filesystem to the local
btrfs. Cached mem tends to hang out around 26-30GB, but with 4.7.2 the
OOM is now going crazy and trying to kill whatever it can including my ssh and
rsync process. Anyone seen anything similar?
Trying it again with /proc/sys/vm/swappiness at 0 will see if that makes a
difference.

Yes, I had the same issue on a backup VM that only has 1G ram - rsync constantly is killed by OOM. Doesn't happen on the main machine with 24G ram.

Paul.
