nfsd4_block_...de_layoutget(9)

💅 nfsd4_block_encode_layoutget — like, the whole vibe ✨

okay so bestie, you're in the Kernel API Manual and today's main character is nfsd4_block_encode_layoutget(9). Buckle up 🎀

---

🌸 NAME 🌸

nfsd4_block_encode_layoutget — encode a block/scsi layout extent array. that's it, that's the job, and she does it flawlessly 💅

---

✨ SYNOPSIS ✨

__be32 nfsd4_block_encode_layoutget (struct xdr_stream *xdr , const
       struct nfsd4_layoutget *lgp );

so we return a __be32 (iykyk, that's the nfs error code situation) and we take two things. slay.

---

🦋 ARGUMENTS 🦋

• xdr — the stream for data encoding. it's the little conveyor belt the data gets written onto, no cap.
• lgp — the layoutget content, which is actually an array of extents to encode. yes bestie, an array. multiple extents. she's not doing just one 🙈

---

💖 DESCRIPTION 💖

okay so the whole point: this function encodes the opaque loc_body field in the layoutget response. that's the assignment, that's what she ate 🔥

and here's the tea ☕ — the pnfs_block_layout4 and pnfs_scsi_layout4 structures on the wire are the same, literally identical, so both layout drivers use this one function. one function, two drivers, zero notes. iconic behavior honestly 👑

⭐ Return values ⭐

• nfs_ok — success!! all the extents got encoded into xdr, every single one, she left nothing behind 🫶
• nfserr_toosmall — not enough space in xdr to encode all the data 😭 the conveyor belt ran out of room, tragic, truly tragic

• nfsd4_scsi_decode_layoutupdate(9) — and the scsi decode one too, we love a matching set 💜
