💅 dm_test_even...ips_null_dev(9) — Kernel API Manual ✨

okay so bestie, welcome to the kernel API manual page for dm_test_even...ips_null_dev(9) — yeah the title's a little truncated, it's giving dramatic ellipsis energy, but we move 💖

🌸 NAME 🌸

dm_test_event_property_update_skips_null_dev — literally "missing device is skipped", that's the whole vibe 🦋

✨ SYNOPSIS ✨

void dm_test_event_property_update_skips_null_dev (struct kunit *test );

no cap, that's the whole signature 👑

🎀 ARGUMENTS 🎀

  • test — the KUnit test context. it's the little test harness bestie that holds everything together 🫶

💅 DESCRIPTION 💅

okay so picture this: you've got a connected connector that has state but no drm_device. and the rule is — it must be skipped before the modeset lock even gets touched. the way that works out is encryption_status stays exactly the same, untouched, unbothered, main character energy 🌈

so like, nothing happens to it. on purpose. that's the test. periodt 💀

🦋 SEE ALSO 🦋

first up, the kernel file itself, she lives here:
