nfsd_get_dir_deleg(9)

💅 nfsd_get_dir_deleg — like, the Kernel API Manual one, section 9, bestie ✨

okay so picture this: it's a manpage, right, and it's called nfsd_get_dir_deleg, and it lives in section 9 of the Kernel API Manual. that's the whole vibe. now let's get into it 🫶

---

🌸 NAME 🌸

nfsd_get_dir_deleg — the one where we attempt to get a directory delegation. attempt!! it's giving "we're gonna try, no promises" energy 💀

---

✨ SYNOPSIS ✨

struct nfs4_delegation * nfsd_get_dir_deleg (struct nfsd4_compound_state
*cstate , struct nfsd4_get_dir_delegation *gdd , struct nfsd_file *nf );

three args, one function pointer return, literally iconic. copy it exactly, don't @ me 💖

---

🎀 ARGUMENTS 🎀

• cstate — the compound state. that's it, that's the whole description, and honestly? she said what she said.
• gdd — the GET_DIR_DELEGATION arg/resp structure. arg and resp, she does both, main character energy fr fr 👑
• nf — an nfsd_file that's been opened on the directory. like, the actual file handle for the dir in question 🗂️

---

🦋 DESCRIPTION 🦋

so you hand her a GET_DIR_DELEGATION request — that's gdd — and she will attempt to acquire a delegation on the directory that nf refers to. that's the mission. that's the whole plot. no cap ✨

lowkey note the word "attempt" bestie — this is a try, not a guarantee, and i will not be elaborating because the original didn't 😭

okay so this is the part where she name-drops literally everyone in the group chat. the kernel file is ./fs/nfsd/nfs4state.c, and the whole squad is:

that's the whole page, bestie, you ate that 🍓 and real quick, the cute little sign-off the original had tucked at the bottom: this one comes from ./fs/nfsd, dated October 2026, and it's filed under nfsd_get_dir_deleg(9). bye bestie, go read some kernel source 🧚💜
