kiocb_end_write(9)

💅 kiocb_end_write — a kernel API manual moment

okay so welcome to the kiocb_end_write(9) page, bestie, this is from the Kernel API Manual and it's short but she's important. Buckle up 🎀

---

✨ NAME ✨

kiocb_end_write — drop write access to a superblock after async file io

like, you were holding the write vibe and now you're letting it go 🦋

---

✨ SYNOPSIS ✨

void kiocb_end_write (struct kiocb *iocb );

that's it. that's the whole function. no return value, she just does the thing and leaves 💅

---

✨ ARGUMENTS ✨

• iocb — the io context we submitted the write with (yes the original page spells it "sumbitted", we're keeping the energy, it's iconic 😭)

---

✨ DESCRIPTION ✨

okay so this one is lowkey a pair situation. kiocb_end_write should be matched with a call to kiocb_start_write — they're a matching set, a duo, main character energy together 👑

you start the write, you end the write, the superblock's write access gets dropped, everybody goes home. no cap. ✨

no fr like genuinely — if you call one without the other, that's not the vibe. they go together or not at all 💀
