nfs3_decode_dirent(9)

✨ nfs3_decode_dirent(9) ✨

okay so this is a page straight out of the Kernel API Manual, and honestly? it's a little banger. it's about pulling one (1) single NFSv3 directory entry out of the local page cache. one. single. entry. queen behavior 💅

---

🌸 NAME 🌸

nfs3_decode_dirent — decodes a single NFSv3 directory entry that's chillin' in the local page cache 🗂️✨

---

🦋 SYNOPSIS 🦋

int nfs3_decode_dirent (struct xdr_stream *xdr , struct nfs_entry *entry
, bool plus );

---

🎀 ARGUMENTS 🎀

• xdr — the XDR stream where the entry is living its best life. that's where it resides, bestie 💜
• entry — the buffer you fill in with the entry data. it's giving "empty cup, please pour" 🍓
• plus — a boolean that says whether this should be a readdirplus entry or not. yes/no energy 🔥

---

👑 DESCRIPTION 👑

so like. it returns zero if everything went good, and if not? you get a negative errno value back. no cap, that's the whole success metric 😭

big important vibe check: this function is not invoked during READDIR reply decoding. not even a little. instead, it gets called whenever an application invokes the getdents(2) system call on a directory that's already in our cache. main character energy fr fr 🫶

struct entry3 {
        fileid3         fileid;

        cookie3         cookie;
        fhandle3        filehandle;

lowkey if you're poking at this, you're probably deep in the NFS mines. slay. drink some water 💖

🧚 and that's the whole page! this cutie came from ./fs/nfs, dated October 2026 — so go forth and decode those dirents, bestie. periodt. 🎀✨
