Re: OOM killer invoked during btrfs send/recieve on otherwise idle machine

[Chris Murphy]

Yesterday I saw oom killer knocking off processes during a simple cp
-a from one Btrfs to another, in a VM, with kernel
4.8.0-0.rc0.git3.1.fc25.x86_64. The call trace looks different than
Markus' so I'm not sure it's the same problem. It's not always
reproducible. It hasn't happened on 4.7.0 though. According ot koji
this is Linux v4.7-6438-gc624c86

This is 'journalctl -o short-monotonic -b-4 -k'
