[Qemu-devel] [PATCH v3 0/3] vfio: free data and unmap BARs in instance_finalize

[Paolo Bonzini <pbonzini@redhat.com>]

Mostly the same as v2;

- patch 1 makes the error paths of vfio_get_device a bit simpler

- patch 2 introduces instance_finalize

- patch 3 makes the freeing of BARs RCU-friendly

Changes from v2:

1) not removing anymore the NULL assignment in vfio_put_base_device

2) patch 1 should "goto out_put" if vfio_populate_device fails (later
changed to "return ret" in patch 2).  The final code doesn't change;
this only matters for bisectability (and even then only in a corner case).

Thanks,

Paolo
