The plugin is guest agnostic and hence we did not want to rely on any kernel provided functions. The plugin uses only the interface provided by the shell. The assumption is that since the plugin is really simple and straight forward (all the control/init complexity lies in the PF driver in the hypervisor) we should be able to get by for most of the things and for things like memcpy/memset the plugin can write simple functions like this.

Is there some reason that our in-kernel functions that do this type of
logic are not working for you to require you to reimplement this?
