prb_for_each_record(9)

✨ NAME ✨

okay so this is prb_for_each_record(9) from the Kernel API Manual, and it is literally a macro for iterating over the records of a ringbuffer. bestie, it's giving “loop through ringbuffer records, but make it convenient.” 💅

🎀 SYNOPSIS 🎀

prb_for_each_record (from , rb , s , r );

---

💅 ARGUMENTS 💅

• from — the sequence number to begin with, bestie.
• rb — the ringbuffer you're iterating over. iconic.
• s — a u64 to store the sequence number on each iteration.
• r — a printk_record to store the record on each iteration.

🧚 DESCRIPTION 🧚

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

heads up though: s may not be the sequence number of the record on each iteration. not me assuming it is 😭 if you actually need the sequence number, you should check r->info->seq.

🌈 CONTEXT 🌈

Any context. literally any. ✨
