🌸 NAME 🌸

bio_start_io_acct — start I/O accounting for bio based drivers

Like, it literally kicks off the accounting for drivers that work with bios. That's the whole vibe check 💅

---

🦋 SYNOPSIS 🦋

unsigned long bio_start_io_acct (struct bio *bio );

That's it. That's the whole signature. One argument, one unsigned long coming back at you 🫶

🎀 ARGUMENTS 🎀

• bio — the bio you wanna start accounting for. That's the one, bestie, that's your guy 💖

✨ DESCRIPTION ✨

So like, what does it actually do? It returns the start time 📖 — and here's the important part: that start time is the thing you gotta pass back to bio_end_io_acct. So don't lose it, don't toss it, don't leave it on read 🙈

That's genuinely the whole description. Short and sweet, periodt 💅
