__bio_integrity_endio(9)

💖 __bio_integrity_endio — the Kernel API Manual ✨

okay so bestie, we're looking at __bio_integrity_endio(9) today — that's the Integrity I/O completion function and honestly? she's got main character energy 🎀 (the (9) is just the manual section, iykyk)

---

🌸 SYNOPSIS 🌸

bool __bio_integrity_endio (struct bio *bio );

that's it. that's the whole vibe. one bio, one bool back 💅

🦋 ARGUMENTS 🦋

• bio — the Protected bio 🫶 like, the bio that's being protected. that's her job. that's what she does.

⭐ DESCRIPTION ⭐

okay so normally, I/O completion is done in interrupt context. like, that's the standard, that's the default, no cap.

but — and this is the plot twist 😭 — verifying I/O integrity is a time-consuming task, and it must be run in process context. so you literally cannot just do it in interrupt context, it's giving "wrong place, wrong time."

so what does this function do? it postpones completion accordingly. literally that's it. she delays the completion so the integrity verification can happen where it needs to happen. iconic behaviour, honestly 👑

💀 no cap: if you were hoping she'd just finish the I/O right there in interrupt context — she won't. that's the whole point, bestie. the postponing is the feature.
