restart_ctrlq(9)

💅 restart_ctrlq — Kernel API Manual

okay so bestie, welcome to restart_ctrlq(9), a page from the Kernel API Manual, and honestly? It's a little one but it serves. Let's get into it.

---

✨ NAME ✨

restart_ctrlq — restart a suspended control queue. that's it, that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

void restart_ctrlq (struct tasklet_struct *t );

literally one function, one pointer, zero drama. 💅

---

🦋 ARGUMENTS 🦋

• t — pointer to the tasklet associated with this handler. yes queen, you gotta hand her the tasklet, that's the whole handshake. 🫶

---

⭐ DESCRIPTION ⭐

Resumes transmission on a suspended Tx control queue.

that's the entire description and honestly? iconic brevity. the control queue was suspended, this function wakes it back up and transmission resumes on the Tx control queue. no cap. 🔥
