🎀 dm_test_ver...d_bad_shaper(9) 🎀

okay so bestie, welcome to this page from the Kernel API Manual — it's giving kernel-test energy, and we're literally about to vibe-check a bad shaper LUT. 💅✨

💖 NAME 💖

dm_test_verify_lut3d_bad_shaper — Shaper LUT with wrong size: must return -EINVAL

This one is iconic: the shaper LUT has the wrong size, and the test says it must return -EINVAL. No cap, that's the whole assignment. 🫶

✨ SYNOPSIS ✨

void dm_test_verify_lut3d_bad_shaper (struct kunit *test );

🌸 ARGUMENTS 🌸

• test — KUnit test context. That's the context the test runs inside, periodt. 🧚
