[Xen-devel] [RFC/PATCH v6 2/2] tools: XENMEM_claim_pages (subop of existing) hypercall

[Dan Magenheimer <dan.magenheimer@xxxxxxxxxx>]

This is patch 2of2 of a sixth cut of the patch of the proposed
XENMEM_claim_pages hypercall/subop, taking into account
feedback from Jan and Keir and IanC and Matthew Daley.

As requested by Jan, this is a separate post of the tools
part of the patch.  NOTE: This patch must be applied after
the hypervisor part of the patchset or otherwise may break
the build!

v5->v6:
- no change in this patch (only in patch 1of2)

Thanks for any feedback!
