Subject: [PATCH net-next 0/4] vsock/test: Tests for memory leaks

Series adds tests for recently fixed memory leaks[1]:

d7b0ff5a8667 ("virtio/vsock: Fix accept_queue memory leak")
fbf7085b3ad1 ("vsock: Fix sk_error_queue memory leak")
60cf6206a1f5 ("virtio/vsock: Improve MSG_ZEROCOPY error handling")

First patch is a non-functional preparatory cleanup.

I initially considered triggering (and parsing) a kmemleak scan after each
test, but ultimately concluded that the slowdown and the required
privileges would be too much.
