kunit_kfree_const(9)

📦 version 7.3.1, in nixpkgs unstable

💖 kunit_kfree_const (9) — from the Kernel API Manual 💖

okay so bestie, welcome to the kunit_kfree_const page, brought to you by the Kernel API Manual (yes that's the manual name, i'm not being weird, it's just on the page 🫶). this one's a tiny little function that's lowkey the polite version of free-ing test memory. let's get into it ✨

🌸 NAME 🌸

kunit_kfree_const — conditionally free test managed memory. that's the whole vibe: it frees sometimes. it's a maybe girlie. 💅

✨ SYNOPSIS ✨

void kunit_kfree_const (struct kunit *test , const void *x );

returns nothing, obviously. doesn't want the smoke of an error code 🔥

🎀 ARGUMENTS 🎀

  • test — the test context object. it's the main character of your test, you know her 👑
  • x — pointer to the memory. just a pointer. that's it. that's the whole thing 🦋

🧚 DESCRIPTION 🧚

okay so here's the tea ☕ — this calls kunit_kfree only if x is not in the .rodata section.

that's it. that's the function. it's giving "i'll free it, but only if it's not one of the read-only girlies." 😭

and if you want the full lore on why .rodata matters here, the page literally says to go read kunit_kstrdup_const for more information — so go read that one bestie, it's linked down there 👇

lowkey important: the free is conditional. it does not just free anything you hand it, and no, i'm not elaborating beyond what the page says 🔥

🫶 SEE ALSO 🫶

the kernel file that matters here is ./include/kunit/test.h, and then there's a genuinely iconic amount of related stuff — ngl this list is a whole friend group 💀

like, that's the whole squad. go say hi 🌈

and that's the page!! mwah 💋 this one shipped from the source path ./include/kunit and it's dated October 2026 — so like, mark your calendar bestie, this manual page is from the future and it ate 🎀✨💜
