Hi,
I am not sure, but if we are going to use that function from the
memory-hotplug code,
we might want to rename that function to something more generic?
The word "boot" suggests that this is only called from the boot stage.
I ll rename it to __free_pages_core()
And what about the prefetch operations?
I saw that you removed them in your previous patch and that had some
benefits [1].
Should we remove them here as well?
Sure. Will update this as well.
Thanks,
Arun
