💅 dm_test_hpd_...suspend_null(9) 💅

okay so bestie, we’re in the Kernel API Manual, and this is the page for dm_test_hpd_...suspend_null(9). the actual test name is dm_test_hpd_rx_irq_work_suspend_null, and it’s giving very specific kernel-test energy. slay. ✨

🌸 NAME 🌸

dm_test_hpd_rx_irq_work_suspend_null — Test suspend with no work queue. that’s the vibe: a KUnit test for suspend when there’s no work queue. no cap. 💖

✨ SYNOPSIS ✨

void dm_test_hpd_rx_irq_work_suspend_null (struct kunit *test );

it returns void, and it takes one thing: a struct kunit * named test. iconic. 🫶

🎀 ARGUMENTS 🎀
