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?
