__queue_and_wait(9)

💖 __queue_and_wait(9) 💖

okay bestie, this is a page from the Kernel API Manual, and it's literally about queueing a task and waiting for it to wake up. very main character energy for a kernel function, honestly.

---

🌸 NAME 🌸

__queue_and_wait — queue a task and wait until the task is waked up.

---

✨ SYNOPSIS ✨

void __queue_and_wait (struct ubifs_info *c );

---

🎀 ARGUMENTS 🎀

• c — the UBIFS file-system description object. that's it, that's the argument, and it's iconic.

---

🦋 DESCRIPTION 🦋

so here's the vibe: this function adds the current task in the queue and waits until the task is waked up. periodt.

also, important lock check 🫶: this function should be called with c->reserve_space_wq locked. don't skip that part, bestie, it's giving "required context" and we respect it.
