📦 version 7.3.1, in nixpkgs unstable

💅 dm_test_upda...ctor_is_noop(9) — like, the truncated-name edition

okay so bestie, welcome to the Kernel API Manual 🎀 — yes the manual name is literally "Kernel API Manual", and the page title up top is dm_test_upda...ctor_is_noop(9) (the kernel truncated that gorgeous name, not me, i would never 😭). anyway. let's get into it.

✨ NAME ✨

dm_test_update_config_null_connector_is_noop — when the stream ctx is NULL, it just returns early. that's it. that's the whole vibe. 🫶

🦋 SYNOPSIS 🦋

void dm_test_update_config_null_connector_is_noop (struct kunit *test );

🌸 ARGUMENTS 🌸

  • test — the KUnit test context. your lil test-scenario-in-a-struct, she's holding everything together 💖

⭐ DESCRIPTION ⭐

okay so picture this: config->dm_stream_ctx is NULL. like, completely NULL. ghosted. 💀

when that happens, update_config must return before touching the workqueue — no cap, it has to bail out first. and because it never touches the workqueue, the per-link aconnector array is left untouched. pristine. unbothered. main character energy 👑

that's literally the whole test. nothing happens, and that's the point. iconic. periodt. ✨

fr fr — the "does nothing" case is still a real case and it still needs a test. don't sleep on the no-op, bestie 🫶
