💅 dm_test_rep...power_module(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this is the page for dm_test_rep...power_module(9), and no, the truncation isn't a typo, that's just how the header renders it. The full star of the show is dm_test_replay_set_event_missing_power_module, and she is iconic. Let's get into it 🫶

---

🌸 NAME 🌸

dm_test_replay_set_event_missing_power_module — verify that a missing power module gets properly rejected. literally that's her whole job 💅

---

✨ SYNOPSIS ✨

void dm_test_replay_set_event_missing_power_module (struct kunit *test
);

not me writing void with the line break exactly like the original, iykyk 😭

---

🎀 ARGUMENTS 🎀

• test — the KUnit test context 🧚 that's it, that's the whole argument list, she's low maintenance.

---

🦋 DESCRIPTION 🦋

so here's the vibe check 🌈: this test covers the situation where Replay is enabled but there's no power module available. In that case, the event helper should return false — and it should do that after failing to read the current Replay events. Like, the failure path is the whole point, bestie. She's testing the rejection. periodt 💀
