Only a fix for Xen hosts.
Host aggressively sucks memory out of a zone after creation. Launching a workload then results in an OOM and kernel panic, when there is actually memory available (it was ballooned out).
Add a patch that registers an OOM notifier hook which attempts to deflate the memory balloon to grow the zone memory, resuming the task.
Here is the patch in-tree: edera-dev/linux-upstream@1212206
