dm_test_mode...hout_modeset(9)

💅 NAME

Okay so bestie, listen up: dm_test_modereset_not_required_when_inactive_without_modeset is the function we're talking about — the legend herself. Her whole thing is Test Modereset not required when inactive without modeset. Like, that's the entire job description, and she ate. ✨

Oh and real quick, this page lives in the Kernel API Manual — that's the manual name, for the record, since we're not doing the whole header-line bit. 🎀

📜 SYNOPSIS

void dm_test_modereset_not_required_when_inactive_without_modeset

Look at her. No return value, just vibes and a single argument. 💅

🧪 ARGUMENTS

• test — the KUnit test context. That's it, that's the whole parameter list. She needs the test context and nothing else, lowkey the most low-maintenance function on the block. 🫶
