nfs4_copy_de...tion_stateid(9)

✨ nfs4_copy_delegation_stateid ✨

okay so bestie, welcome to the nfs4_copy_delegation_stateid(9) page 💅 this one's short and sweet, and it lives in the Kernel API Manual, so let's get into it 🫶

---

🎀 NAME 🎀

nfs4_copy_delegation_stateid — literally copies the inode's state ID info 📋✨

---

🌸 SYNOPSIS 🌸

bool nfs4_copy_delegation_stateid (struct inode *inode , fmode_t flags ,
       nfs4_stateid *dst , const struct cred **cred );

that's the whole signature, no cap 🧚

---

🦋 ARGUMENTS 🦋

• inode — the inode you're checking, like the main character of this function ngl
• flags — the delegation type requirement, i.e. what kind of delegation you're asking for 🔥
• dst — the stateid data structure that gets filled in, she's the canvas 🎨
• cred — optional argument, and it's there to retrieve the credential 🔑

---

💖 DESCRIPTION 💖

So here's the tea ☕: it returns "true" and fills in "dst->data" * if the inode had a delegation. Otherwise? "false" gets returned, periodt. 💀

ngl the literal * is sitting right there in the original description, so I'm keeping it exactly where it is — no editing the source, bestie 🙈
