💅 kunit_remove_action(9) — Kernel API Manual

okay bestie, welcome to the kunit girlies' corner of the kernel docs ✨ this little function is your "never mind, cancel that" button for deferred test cleanup, and honestly? iconic.

🌸 NAME

kunit_remove_action — cancel a matching deferred action. bye-bye, cleanup call 🫶

🎀 SYNOPSIS

void kunit_remove_action (struct kunit *test , kunit_action_t *action ,
void *ctx );

literally three things and you're done 💅

🦋 ARGUMENTS

  • test — the test case this action is associated with. it's her test, the action belongs to her 👑
  • action — the deferred function you want to cancel. the one you're ghosting 🙈
  • ctx — the context that gets passed to the deferred function to trigger it. like, the exact vibe that makes the match happen ✨

💖 DESCRIPTION

so the whole point: you stop an action that was deferred via kunit_add_action from executing when the test terminates. no more surprise cleanup at the end of the test — you said no, and you meant it 💀

⚠️ real talk though: if that function/context pair was deferred multiple times, only the most recent one gets cancelled. not all of them. just the newest one. the rest are still showing up to the party 😭 so don't come for me when your older registrations still fire — them's the rules, fr fr.

See also: devm_remove_action for the devres equivalent — same energy, different subsystem 🧚

🌈 that's the whole page, bestie — go forth and cancel your deferred actions responsibly 💜

sign-off era: this one lives in ./include/kunit, dated October 2026, and it's giving "kernel api manual" realness 🎀 mwah 💋
