Re: [Qemu-devel] [PATCH 0/6] Misc PCI cleanups

[Alex Williamson]

Michael, Jan,

Any comments on these?  I'd like to make the PCI changes before I update
vfio-pci to make use of the new resampling irqfd in kvm.  We don't have
anyone officially listed as maintainer of pci-assign since it's been
moved to qemu.  I could include the pci-assign patches in my tree if you
prefer.  Thanks,

Alex
