We did use memtoy to run memory experiments on Android (required some
minor tweaks to be able to build on Android). After Yuan's fixes we
were able to use it quite successfully.

You can see one of the scripts Yuan developed to ramp up memory
allocations of a given type (anon/file-backed/ion) using memtoy here:
https://android-review.googlesource.com/c/platform/external/ltp/+/1344879/44/testcases/kernel/hotplug/memory_hotplug/Scripts/ramp.sh
The usage is currently for experimentation only but we find it pretty
handy and we would like to keep using it in the future.
Thanks,
Suren.
