okay so this is a page from the Kernel API Manual, section 9 — yes bestie, section 9, kernel-level stuff, we're in the big leagues now 🫶

✨ NAME ✨

svcxdr_tmpalloc — allocate memory to be freed after compound processing

no cap, that's the whole vibe: you grab some memory, and it gets yeeted once the compound processing wraps up 💅

---

🌸 SYNOPSIS 🌸

void * svcxdr_tmpalloc (struct nfsd4_compoundargs *argp , size_t len );

literally the whole signature, character for character, don't come for me 🎀

---

🦋 ARGUMENTS 🦋

• argp — the NFSv4 compound argument structure 👑 like, the whole context of the compound op lives here
• len — length of buffer to allocate 📏 how many bytes you're asking for

---

💜 DESCRIPTION 💜

So here's the tea: svcxdr_tmpalloc allocates a buffer of size len, and that buffer is set to be freed when the processing of the compound operation described in argp finishes. 🧚

that's it, that's the function. temporary by design, iconic by nature ✨ it's giving "borrowed memory, but make it polite" — it cleans up after itself so you don't have to 😭

lowkey important: the freeing is tied to the compound operation in argp finishing. that's the whole contract, bestie, don't forget it 💀
