prb_final_commit(9)

💅 prb_final_commit(9) — the Kernel API Manual glow-up

okay bestie, welcome to prb_final_commit, straight out of the Kernel API Manual. This is the moment your reserved data gets its main character arc — it's been sitting there reserved and now it's time to commit and finalize, periodt. 🎀

✨ NAME ✨

prb_final_commit — commit and finalize (previously reserved) data to the ringbuffer. Like, the reservation is finally getting posted, no cap. 🦋

🌸 SYNOPSIS 🌸

void prb_final_commit (struct prb_reserved_entry *e );

💖 ARGUMENTS 💖

• e — the entry holding all the reserved data information. That's your little envelope of reserved-data lore. Keep it close. 🫶

✨ DESCRIPTION ✨

Okay so this is the public function that's available to writers so they can commit + finalize their data. It's giving "final step, let's gooo." 🔥

By finalizing, the data is made immediately available to readers. Like, instantly. Readers can see it the second you finish. Slay.

Use this function only if you have no intentions of extending this data using prb_reserve_in_last. If you do plan to extend it — bestie, put it down, this is not the move. 💀

🧚 CONTEXT 🧚

Any context. Yep, any — it's flexible like that. ✨ And jsyk, it enables local interrupts.
