Subject: [PATCH net-next v2 00/12] selftests/vsock: refactor and improve
 vmtest infrastructure

Hey all,

This patch series refactors the vsock selftest VM infrastructure to
improve test run times, improve logging, and prepare for future tests
which make heavy usage of these refactored functions and have new
requirements such as simultaneous QEMU processes.

These patches were broken off from this prior series:
https://lore.kernel.org/all/20251021-vsock-vmtest-v7-0-0661b7b6f081@meta.com/

---
Changes in v2:
- remove "Fixes" for some patches because they do not fix bugs in
  kselftest runs (some fix bugs only when using bash args that kselftest
  does not use or otherwise prepare functions for new usage)
- broke out one fixes patch for "net"
- per-patch changes
- add patch for shellcheck declaration to disable false positives
- Link to v1: https://lore.kernel.org/r/20251022-vsock-selftests-fixes-and-improvements-v1-0-edeb179d6463@meta.com
