nfs4_inode_r...n_delegation(9)

💅 nfs4_inode_return_delegation(9) — from the Kernel API Manual, bestie ✨

okay so this one's a kernel API page, it lives in the <pink>Kernel API Manual</pink>, and the whole name got squished to nfs4_inode_r...n_delegation(9) on the tin — you know how man pages do when the title's too long for the header. iconic of them honestly.

---

🎀 NAME 🎀

nfs4_inode_return_delegation — returns a delegation, and it does it synchronously, no "i'll get to it later" energy 💅

---

✨ SYNOPSIS ✨

void nfs4_inode_return_delegation (struct inode *inode );

---

🦋 ARGUMENTS 🦋

• inode — the inode we're processing. that's the one, that's our girl, she's the whole assignment 🫶

---

🌸 DESCRIPTION 🌸

so this routine is lowkey committed: it will always flush any dirty data to disk. like, no negotiating, no vibe check first — the logic being that if we've ended up needing to return the delegation, then we should stop caching. periodt. 💀

it returns zero on success, or a negative errno value. the synopsis says void and the description says it returns things — yeah, i noticed too, don't @ me, i'm just the messenger 🧚 ngl that's the docs' business, not mine.
