✨ prb_for_each_info(9) ✨

okay bestie, this is the Kernel API Manual page for prb_for_each_info, and it's lowkey giving “iterate over ringbuffer meta data” main character energy. 💅

🌸 NAME 🌸

prb_for_each_info — iterate over the meta data of a ringbuffer. iconique. 🎀

🦋 SYNOPSIS 🦋

prb_for_each_info (from , rb , s , i , lc );

💖 ARGUMENTS 💖

• from — the sequence number to begin with. your starting point, bestie. ✨
• rb — the ringbuffer to iterate over.
• s — a u64 to store the sequence number on each iteration.
• i — a printk_info to store the record meta data on each iteration.
• lc — an unsigned int to store the text line count of each record.

🌈 DESCRIPTION 🌈

This is a macro for conveniently iterating over a ringbuffer. no cap, that's the whole vibe. 🫶

heads up bestie: s may not be the sequence number of the record on each iteration. for the sequence number, i->seq should be checked. 👀💅

👑 CONTEXT 👑

Any context. literally any context, she's flexible. 💜
