[PATCH 0/2] vhost-vdpa: fix issues around v->config_ctx handling

While writing a test for a Rust library [1] to handle vhost-vdpa devices,
I experienced the 'use-after-free' issue fixed in patch 1, then I
discovered the potential issue when eventfd_ctx_fdget() fails fixed in
patch 2.

Do you think it might be useful to write a vdpa test suite, perhaps using
this Rust library [2] ?
Could we put it in the kernel tree in tool/testing?

Thanks,
Stefano
