💅 kunit_deactivate_static_stub(9) — like, the whole vibe

okay bestie, so this is a page straight out of the Kernel API Manual, and it's about undoing a function redirection. Yes, undoing. We love a clean exit. 🎀

---

✨ NAME ✨

kunit_deactivate_static_stub — disable a function redirection. That's it, that's the tweet. 💅

---

🌸 SYNOPSIS 🌸

void kunit_deactivate_static_stub (struct kunit *test , void
*real_fn_addr );

literally just those two args, no cap. 🦋

---

🫶 ARGUMENTS 🫶

• test — a pointer to the struct kunit test context for the current test. like, which test are we doing this for, bestie? that one. ✨
• real_fn_addr — the address of the function to no-longer redirect. the og function. the real one. the main character. 👑

---

🔥 DESCRIPTION 🔥

So here's the tea ☕: this function deactivates a redirection configured with kunit_activate_static_stub.

Once this function returns, calls to real_fn_addr will execute the original real_fn — not any previously-configured replacement. periodt. 💀

it's giving "we're done pretending now, back to reality." no lingering stubs, no weird ghost behaviour, just the actual function doing its actual job again. slay. 🌈
