Subject: [PATCH net v2 0/2] af_unix: Fix GC and improve selftest

Series deals with AF_UNIX garbage collector mishandling some in-flight
graph cycles. Embryos carrying OOB packets with SCM_RIGHTS cause issues.

Patch 1/2 fixes the memory leak.
Patch 2/2 tweaks the selftest for a better OOB coverage.

v2:
  - Patch 1/2: remove WARN_ON_ONCE() (Kuniyuki)
  - Combine both patches into a series (Kuniyuki)

v1: https://lore.kernel.org/netdev/20240516103049.1132040-1-mhal@rbox.co/

Kuniyuki Iwashima (1):
  selftest: af_unix: Make SCM_RIGHTS into OOB data.

Michal Luczaj (1):
  af_unix: Fix garbage collection of embryos carrying OOB with
    SCM_RIGHTS
