nfs_fhandle_hash(9)

💖 nfs_fhandle_hash(9) — Kernel API Manual, section 9, bestie 💖

okay so real talk, this one is a tiny little function from the Kernel API Manual (section 9, the kernel-adjacent girlies know 👑) and it does exactly one thing, but it does it flawlessly. No notes. Let's get into it ✨

---

🌸 NAME 🌸

nfs_fhandle_hash — calculate the crc32 hash for the filehandle @fh — pointer to filehandle 💅

like, that's the whole job. she hashes filehandles. she's an icon and she knows it.

---

🎀 SYNOPSIS 🎀

u32 nfs_fhandle_hash (const struct nfs_fh *fh );

that's it. that's the whole call. a u32 walks in, a const struct nfs_fh * walks out… no wait, the other way around, you get it 😭

---

🦋 ARGUMENTS 🦋

• fh — okay so the manpage literally just says -- undescribed -- for this one 🙈 not me exposing the docs, but fr fr that's all the original gives us. it's the pointer to the filehandle (that part's in the NAME line, iykyk). we are not going to invent lore that isn't there, bestie. no cap.

---

✨ DESCRIPTION ✨

so what she does: she returns a crc32 hash for the filehandle — and the vibe check here is that it's compatible with the one displayed by "wireshark". 🔥

like yes, that's the whole bit. you hash the fh, wireshark shows the same hash, you two are matching. matching energy. main character compatibility. 💖

---

💜 SEE ALSO 💜

• Kernel file ./include/linux/nfs.h — go read it, it's giving lore 🫶

🧚 tiny reminder from your girl: the description really is that short in the og, so don't @ me about missing details — every single one of them is right here, periodt.
