💅 NAME (aka what even is this)

okay so this page is from the Kernel API Manual, and the page itself is dm_test_bri...ser_midrange(9) (yes the title is truncated, she's mysterious like that ✨). What it actually documents is:

dm_test_brightness_from_user_midrange — a lil test that tests Brightness from user mid-range value, no cap 💖

🎀 SYNOPSIS (the signature, look at her)

void dm_test_brightness_from_user_midrange (struct kunit *test );

that's it. that's the whole vibe. returns void, takes exactly one thing 🫶

🌸 ARGUMENTS (the one and only parameter)

  • test — the KUnit test context. that's her whole personality. it's the test-context bestie that comes along for the ride 🧚

🦋 SEE ALSO (the group chat, and it's a BIG group chat)
