[Qemu-devel] [PATCH v2 0/3] vfio: free data and unmap BARs in instance_finalize

[Paolo Bonzini <pbonzini@redhat.com>]

This is v2 of the patch sent yesterday.  In addition to including
the missing vfio bits, I split it in two parts: one introducing
instance_finalize (patch 2), and the second making the freeing of BARs
RCU-friendly (patch 3).

With these two changes I found the error path logic a bit hard
to follow.  So I preceded it with patch 1, which tries to make things
a little bit clearer, at least to me.

VFIO is probably the device that requires the largest changes, due to
the complex, highly data-driven initialization sequence.  No other device
can use so many dynamic data structures, because their configuration is
obviously not as variable as for PCI pass-through.
