dm_test_irq_..._null_params(9)

okay so bestie, welcome to the dm_test_irq_..._null_params(9) page from the Kernel API Manual 💖 — it’s giving tiny-but-iconic kernel test energy.

💅 NAME 💅

dm_test_irq_register_rejects_null_params — test register rejects null params.

That’s the whole name, no cap. This test is literally about register rejecting null params, and the manual page is short and sweet about it. Slay.

✨ SYNOPSIS ✨

void dm_test_irq_register_rejects_null_params (struct kunit *test );

🫶 ARGUMENTS 🫶

• test — the KUnit test context. That’s the one and only thing it takes, bestie.
