dm_test_veri..._valid_gamma(9)

🌸 NAME 🌸

okay so bestie, this is the manual page for dm_test_veri..._valid_gamma(9) in the Kernel API Manual — and the whole vibe is literally: dm_test_verify_lut_sizes_invalid_degamma_valid_gamma — Bad degamma overrides valid gamma: -EINVAL ✨ no cap, that's the name and the mood.

✨ SYNOPSIS ✨

the signature is giving "tiny but important", periodt:

void dm_test_verify_lut_sizes_invalid_degamma_valid_gamma (struct kunit
*test );

🎀 ARGUMENTS 🎀

• test — KUnit test context. that's it, that's the whole argument list, bestie 🫶
