Hi Ahmed! I put together a selftest for maintaining the affinity: https://github.com/kuba-moo/linux/commit/de7d2475750ac05b6e414d7e5201e354b05cf146 It depends on a couple of selftest infra patches (in that branch) which I just posted to the list. But if you'd like you can use it against your drivers.
