dm_test_enco...disable_noop(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dm_test_enco...disable_noop(9) — like, the whole vibe ✨

okay bestie, welcome to the Kernel API Manual, section 9 (kernel developer stuff, iykyk). today's main character is dm_test_enco...disable_noop, yes that's the literal truncated name, no we're not fixing it, it's iconic 💀

🌸 NAME 🌸

dm_test_encoder_disable_noop — it tests that the disable hook is, and I cannot stress this enough, a literal no-op 🫶

✨ SYNOPSIS ✨

void dm_test_encoder_disable_noop (struct kunit *test );

🎀 ARGUMENTS 🎀

  • test — the KUnit test context, bestie. that's the whole thing. that's the argument. 🦋

💖 DESCRIPTION 💖

so here's the tea ☕: dm_encoder_helper_disable has an empty body. like, genuinely empty. nothing in it. it's giving minimalism, it's giving "I have nothing to say."

and the rule is — calling it must neither touch the encoder nor crash. that's it. that's the entire test. no encoder poking, no crashing, just vibes. if it touches the encoder or explodes, the test fails and we're all sad 😭💅

bestie, that's the whole list. every single one. I counted, you count, we all count. no skipping the "boring" ones, that's not the vibe here 💀✨
