dm_test_link...ily_disabled(9)

💅 NAME

Okay so bestie, welcome to the dm_test_link...ily_disabled(9) page, straight out of the Kernel API Manual 👑 — and the actual function it's serving is dm_test_link_supports_psrsu_temporarily_disabled, which lowkey does exactly what it says on the tin:

dm_test_link_supports_psrsu_temporarily_disabled — supported panels still return false while PSR-SU is temporarily disabled. No cap, that's the whole vibe check ✅

✨ SYNOPSIS ✨

void dm_test_link_supports_psrsu_temporarily_disabled (struct kunit
test );

Like… that's it. One function, one arg, done 🎀

🎀 ARGUMENTS 🎀

• test — the KUnit test context 💖 that's literally all it takes, she's low maintenance.
