Interesting, thanks. Patch doesn't apply clean to 4.7.2, but I get the
gist, delete one version of should_compact_retry() and move ifdef so
it only has __alloc_pages_direct_compact(). I'll try it out if my
rsync gets OOM'd again.

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
