💅 dm_test_event_callback_schedules_property_validate 💅

okay so bestie, you're looking at dm_test_even...rty_validate(9) from the Kernel API Manual — yes that's the real abbreviated page name, the full function name is a whole mouthful and we love that for her. Sit down, hydrate, let's get into it 🫶

🌸 NAME 🌸

dm_test_event_callback_schedules_property_validate — the test that checks process_output() actually runs. periodt ✨

🎀 SYNOPSIS 🎀

void dm_test_event_callback_schedules_property_validate (struct kunit
*test );

no return value, no drama, just vibes 💅

🦋 ARGUMENTS 🦋

  • test — the KUnit test context. that's her little backstage pass 🎟️

⭐ DESCRIPTION ⭐

so here's the tea ☕ — event_callback finishes up its whole thing by calling process_output, and process_output always enqueues property_validate_dwork with delay=0. every single time. no cap.

so when this test peeks in and verifies that the dwork is pending? that's the whole proof right there 🔥 it proves event_callback actually reached process_output and that it released the mutex. two-for-one confirmation, we stan a test that multi-tasks 👑

ngl, it's giving forensic detective work and I'm kind of obsessed 🕵️‍♀️

and that's the whole page, bestie 🍓 tysm for reading, hope the dwork is always pending in your favor 💜
