kfifo_reset(9)

💖 kfifo_reset(9) — Kernel API Manual, group-chat edition 💖

🌸 NAME 🌸

kfifo_reset — removes the entire fifo content. That’s the whole assignment, and honestly? It ate. 💅 The fifo content is gone, bestie. Entirely.

---

✨ SYNOPSIS ✨

kfifo_reset (fifo );

Lowkey the whole call is right there — yes, with fifo in the parentheses. 🎀

---

🫶 ARGUMENTS 🫶

• fifo — address of the fifo to be used. Like, the actual address. No cap. 🦋

---

🚨 NOTE 🚨

🚨 DANGER, DANGER, BESTIE: usage of kfifo_reset is dangerous. It should be only called when the fifo is exclusived locked or when it is secured that no other thread is accessing the fifo. This is not a drill, and it is definitely not a “yeet it and hope” situation. 😭
