✨ dm_test_process_output_callback_stop(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 — this one's a lil' KUnit test helper and honestly? she's short but she SERVES. let's get into it 🎀

🌸 NAME 🌸

dm_test_process_output_callback_stop — the function whose whole personality is "callback_stop cancels callback_dwork" 💅 like that's literally her job and she does it.

🦋 SYNOPSIS 🦋

void dm_test_process_output_callback_stop (struct kunit *test );

no cap, that's the whole signature. returns void, takes one thing, moves on. iconic behavior tbh ✨

🍓 ARGUMENTS 🍓

  • test — the KUnit test context 🧪. that's it. that's the vibe. she needs her test framework bestie to exist and then she's good to go 🫶

👑 DESCRIPTION 👑

okay so here's the tea ☕ — when output.callback_stop is true, process_output must cancel a previously scheduled callback_dwork. that's the entire assignment. not me being dramatic, that's literally what it says 💀

like, callback_stop says "we're stopping bestie" and so process_output has to go cancel that callback_dwork that got scheduled earlier. no lingering dwork. no zombie work items. we clean UP. periodt 🌈

lowkey the most straightforward test in the whole file and honestly? sometimes that's the most iconic thing you can be 💜
