💅 dm_test_atom..._state_empty(9)

okay so bestie, welcome to the Kernel API Manual ✨ — we're talking about dm_test_atomic_get_new_state_empty today, and honestly? it's giving tiny-but-iconic. 🎀

🌸 NAME 🌸

dm_test_atomic_get_new_state_empty — this one tests that an empty atomic state has no DM state, periodt. 💅

---

✨ SYNOPSIS ✨

void dm_test_atomic_get_new_state_empty (struct kunit *test );

like, that's the whole signature. nothing extra. no notes. 🫶

🦋 ARGUMENTS 🦋

• test — the KUnit test context 💖 (yes, that's it, that's the whole argument list, she's low-maintenance)
