π dm_test_should_create_sysfs_non_edp β the Kernel API Manual moment β¨
okay so bestie, welcome to the glow-up of dm_test_sho...ysfs_non_edp(9) β that's the Kernel API Manual entry, and honestly? she's a whole vibe. sit down, hydrate, and let's get into it π«Ά
β¨ NAME β¨
dm_test_should_create_sysfs_non_edp β the test that checks non-eDP connector disables sysfs. that's the entire lewk, no notes π
π¦ SYNOPSIS π¦
void dm_test_should_create_sysfs_non_edp (struct kunit *test );
literally one line, one function, zero drama. copy it exactly, bestie, character for character β we do not freestyle signatures in this house π
πΈ ARGUMENTS πΈ
testβ the KUnit test context. that's it, that's the whole squad. she shows up, she does her job, she slays π
