KUNIT_ASSERT_PTR_NE(9)

📦 version 7.3.1, in nixpkgs unstable

✨ KUNIT_ASSERT_PTR_NE — a Kernel API Manual moment ✨

okay so bestie, this is a kernel API page, and the star of the show is KUNIT_ASSERT_PTR_NE 💅 (with a lil cameo from KUNIT_ASSERT_PTR_EQ — we'll get to that, don't worry 🫶).

🌸 NAME 🌸

KUNIT_ASSERT_PTR_NE — asserts that pointers @left and @right are not equal. 🔥

Also living on this page: KUNIT_ASSERT_PTR_EQ() — asserts that pointers @left and @right are equal. Yeah, it's the mirror-twin situation, iconic behavior honestly ✨

🦋 SYNOPSIS 🦋

KUNIT_ASSERT_PTR_NE (test , left , right );

literally that's the whole vibe check 👑

🎀 ARGUMENTS 🎀

  • test — the test context object 🧚 (yes it's required, yes it's important)
  • left — an arbitrary expression that evaluates to a pointer 🌈
  • right — an arbitrary expression that evaluates to a pointer 🌈

two arbitrary pointer-y expressions, walking into a test, no cap 💀

💖 DESCRIPTION 💖

So what it does: it sets an assertion that the values that left and right evaluate to are not equal. That's it, that's the gig 💅

It's the same as KUNIT_EXPECT_NE, except — and this is the main character detail — it causes an assertion failure when the assertion is not met (see KUNIT_ASSERT_TRUE). 😭 So like, it's not just gonna side-eye the failure and move on; it actually fails.

🚨 friendly heads-up bestie: "assertion failure" means the test does not simply shrug. If you wanted the chill version, that's KUNIT_EXPECT_NE. If you want the "this must be true or we're done here" energy, this is it.

🔥 SEE ALSO 🔥

okay this list is LONG but we do not skip, we do not summarize, we list every single one because that's the assignment 🫶

Kernel file ./include/kunit/test.h

like. that's the whole friend group 💜

and that's the page bestie!! 🎀 this one's from ./include/kunit, dated October 2026, and the manual it lives in is KUNIT_ASSERT_PTR_NE(9) — go forth and assert those pointers are not equal, slay 💅✨
