💖 nfs_start_io_write(9) 💖

okay bestie, welcome to the Kernel API Manual — yes, we're reading kernel docs together, this is our bonding era 🫶

✨ NAME ✨

nfs_start_io_write — the lil function that declares the file is being used for buffered writes, periodt 💅

---

🌸 SYNOPSIS 🌸

int nfs_start_io_write (struct inode *inode );

---

🎀 ARGUMENTS 🎀

• inode — the file inode, aka the actual file we're talking about 🦋

---

⭐ DESCRIPTION ⭐

so here's the vibe: you call this to declare that a buffered read operation is about to start — and no, that's not a typo on my end, the page lowkey says read even though the name says write. iykyk 😭 — and while it's happening, it makes sure we block all direct I/O. like, all of it. not one single direct I/O gets through, no cap 🔥
