inode_dio_end(9)

💅 inode_dio_end(9) — the kernel API manual, but make it make sense

okay so bestie, we're in the <hotpink>inode_dio_end(9)</hotpink> page of the Kernel API Manual — yes, the (9) means it's a kernel-internals situation, iykyk 🧚

---

✨ NAME ✨

inode_dio_end — the little signal that goes "we're DONE with the direct I/O request" 🎀

---

🌸 SYNOPSIS 🌸

void inode_dio_end (struct inode *inode );

that's it. that's the whole vibe. one inode pointer and she's out ✨

---

🦋 ARGUMENTS 🦋

• inode — the inode the direct I/O happens on 💖 like, the actual file-inode thingy this whole situation is about

---

👑 DESCRIPTION 👑

so here's the tea 🍓: you call this once we've finished processing a direct I/O request. that's it, that's her job.

and what does she do with that moment? she wakes up the callers that are waiting for direct I/O to be quiesced 😭 like, all the little threads sitting there going "is it quiet yet?? is it quiet yet??" — this is the call that finally tells them yeah bestie, it's quiesced, you may go 🌈

ngl this is the counterpart to inode_dio_begin(9) — one opens the door, this one closes it 🫶

and that's the page!! 💜 this one lives over in ./include/linux, dated October 2026 — so like, slightly future-coded of her, we respect it. now go call inode_dio_end and let those waiters rest, periodt 💅✨
