[Qemu-devel] [RFC post-2.5 PATCH 0/5] VFIO: capability chains

[Alex Williamson <alex.williamson@redhat.com>]

This is the matching QEMU changes for the proposed kernel-side
capability chains.  Unfortunately there's also a lot of churn to get
to consistent interfaces involved in this series, which allow us to
generically handle multiple mmaps overlapping a region and making the
actual step of consuming the new kernel data trivial.  The last patch
shows the proof of concept for reallocating the info buffer when
necessary and finding and using capability data.  Apologies for the
patches being a little rough, but I hope the concept shows through.
As noted above, this is of course post-2.5 material and of course
kernel header updates would only be included when accepted upstream.
Thanks,

Alex
