dm_test_upda...link_is_noop(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

dm_test_upda...link_is_noop — the KUnit test that goes "nope, no dc_link, we're out" 💅 (and yeah, it lives in the Kernel API Manual, hi bestie 🫶)

🌸 SYNOPSIS 🌸

void dm_test_update_config_null_dc_link_is_noop (struct kunit *test );

It's giving void, it's giving "this function returns nothing, the test does the talking" ✨

🦋 ARGUMENTS 🦋

  • test — the KUnit test context 🎀 that's it, that's the whole argument list, she's low maintenance

💖 DESCRIPTION 💖

okay so picture a connector that has no dc_link at all — the vibe is empty, the link is literally missing. a connector without a dc_link must cause update_config to return before it ever registers the connector, which means the aconnector array stays completely untouched 🌈

that's the whole test: confirm the early return happens and nothing gets registered. the array? untouched. the connector? never added. main character energy for the return statement, honestly 👑

ngl this is the "null dc_link" sibling test — same energy as the null-connector one, different missing thing 🙈
