💅 dm_test_dis...imer_aborted(9)

okay bestie so this is a page from the Kernel API Manual and it's all about one very specific little KUnit test — like, hyper-specific, and honestly? iconic behavior. it's giving "one job, does it perfectly." let's get into it ✨

🌸 NAME 🌸

dm_test_dispatch_next_event_timer_aborted — literally the whole personality is: TIMER_ABORTED always returns IMMEDIATE 💖

no cap, that's it, that's the vibe. one flag in, one flag out, no notes.

🎀 SYNOPSIS 🎀

void dm_test_dispatch_next_event_timer_aborted (struct kunit *test );

---

💅 ARGUMENTS 💅

• test — the KUnit test context, aka the little bag of test-scoped goodies the framework hands you 🫶 it's just there so the test suite knows which test is running, yk?
