💅 kunit_err — like, the kunit_err(9) page, bestie

okay so welcome to the Kernel API Manual, bestie 💖 this one's about kunit_err(9) and it's short but it eats. let's go 🫶

✨ NAME ✨

kunit_err — prints an ERROR level message associated with @test. that's it, that's the whole vibe 🎀

✨ SYNOPSIS ✨

kunit_err (test , fmt , ... );

like, you call it, you pass stuff, it prints. iconic behaviour tbh 🌸

✨ ARGUMENTS ✨

  • test — the test context object. your main character test struct, the one holding it all together 👑
  • fmt — a printk style format string. yes, the same classic format-string energy you already know and love 🔥
  • ... — variable arguments. the little extras, the plus-ones, the and friends 🙈

✨ DESCRIPTION ✨

Prints an error level message. lowkey that's it — an error level message, printed. no cap, no extra lore, just a clean little error-level printk moment for your test 💀✨

✨ SEE ALSO ✨

Kernel file ./include/kunit/test.h — that's where all the friends live, go say hi 🦋
