🌸 dm_test_trace_smu_exit_failure_null_ctx(9) 🌸

okay bestie, buckle up — this is a page straight out of the Kernel API Manual, and it's literally about one tiny KUnit test. yes, one. and honestly? she's precious. 💅

---

✨ NAME ✨

dm_test_trace_smu_exit_failure_null_ctx — ngl the name is a whole mouthful, but what she does is "Test Trace smu exit failure null ctx". that's the vibe. that's the assignment. 🎀

---

🦋 SYNOPSIS 🦋

void dm_test_trace_smu_exit_failure_null_ctx (struct kunit *test );

like… that's it. that's the whole signature. short, sweet, void — she gives nothing back and she's not sorry about it. 😭

---

💖 ARGUMENTS 💖

• test — The KUnit test context. this is the little harness bubble she lives inside, okay? hand her the struct kunit * and she's good to go. 🫶
