💅 dm_test_even...ll_connector(9) 💅

okay so bestie, welcome to the Kernel API Manual — literally the group chat where the kernel docs hang out 🫶. this one's about a KUnit test with a very long name, and the vibes are immaculate. let's get into it ✨

🌸 NAME 🌸

dm_test_event_property_validate_skips_null_connector — bestie, this test is the "null entries ignored" queen 👑. that's literally her whole thing. no cap.

🦋 SYNOPSIS 🦋

void dm_test_event_property_validate_skips_null_connector (struct kunit
*test );

yes, that's the whole signature. she's a void, she takes one thing, she doesn't return anything because she's too busy slaying 💅

🎀 ARGUMENTS 🎀

  • test — the KUnit test context 💖. this is the little test-world she lives in, the context object that KUnit hands over so the test can do its thing. iconic, honestly.

🔥 DESCRIPTION 🔥

so here's the scenario bestie: you take every single aconnector entry and set it to NULL. like, all of them. ghost town. nobody home 👻

and in that situation, event_property_validate has exactly two jobs:

  1. it must not schedule property_update_work — don't you dare queue that work, not with nothing to work on, we are not doing that 🙅‍♀️
  2. it must leave encryption_status untouched — hands off, don't touch the status, it stays exactly how it was, periodt 💀

so yeah, the test is basically a vibe check for "can you handle zero connectors without freaking out and scheduling stuff you shouldn't?" and the answer should be yes, gracefully ✅

no cap: this is a guardrail test. if someone's future patch makes event_property_validate schedule work on a null entry or clobber encryption_status, this test is gonna snitch so fast 😭
