nfs_end_io_write(9)

💖 nfs_end_io_write(9) 💖

ok so this is a page from the Kernel API Manual and honestly bestie, it's a short one but it's important, so let's get into it 🫶

---

✨ NAME ✨

nfs_end_io_write — declare that the buffered write operation is done, periodt 💅

---

🌸 SYNOPSIS 🌸

void nfs_end_io_write (struct inode *inode );

that's it. that's the whole signature. she's minimal and she knows it ✨

---

🎀 ARGUMENTS 🎀

• inode — file inode 🦋

(yes that's the entire description in the original, no cap, it's just the file inode. love a low-effort legend honestly 😭)

---

💜 DESCRIPTION 💜

okay so here's the vibe: you call nfs_end_io_write to declare that a buffered write operation is done ✅ and it also releases the lock on inode->i_rwsem 🔓

so like, if nfs_start_io_write(9) is the "i'm going in" moment, this is the "okay i'm done, wrap it up, everybody out" moment 🧚 the write has finished, the lock gets dropped, the main character energy is released back into the world 💫

🚨 reminder bestie: this is the end call. you don't just vibe in here without having started the op — the whole point is it cleans up after itself and unlocks inode->i_rwsem. match your start/end pairs like your outfits fr fr 👑
