ring_buffer_record_on(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖 — ring_buffer_record_on(9) in the Kernel API Manual

ring_buffer_record_on — restart writes into the buffer. that's the whole function, and honestly? iconic behavior. ✨

✨ SYNOPSIS ✨

the signature is literally:

void ring_buffer_record_on (struct trace_buffer *buffer );

🎀 ARGUMENTS 🎀

  • buffer — the ring buffer you're telling to start writes again. your main-character buffer. 🫶

🦋 DESCRIPTION 🦋

okay so bestie, this one re-enables all the writes to the buffer that were disabled by ring_buffer_record_off. it's giving “turn the writes back on” energy. 💅

and no cap, this is different from ring_buffer_record_enable: this one works like an on/off switch, whereas the enable version has to be paired with a disable. iykyk. 🦋
