ring_buffer..._online_cpus(9)

🎀 ring_buffer..._online_cpus(9) 🎀

okay bestie, welcome to the ring_buffer..._online_cpus(9) page from the Kernel API Manual. The title is giving mysterious ellipsis energy, but the function inside is ring_buffer_reset_online_cpus, and she is here to reset a ring buffer per CPU buffer. No cap. 💖

✨ NAME ✨

ring_buffer_reset_online_cpus — reset a ring buffer per CPU buffer. That's the assignment, that's the whole vibe, and she understood it. 💅

📜 SYNOPSIS 📜

void ring_buffer_reset_online_cpus (struct trace_buffer *buffer );

🫶 ARGUMENTS 🫶

• buffer — the ring buffer to reset a per cpu buffer of, bestie. That's the one and only argument, and yes, she's the main character. 🌸
