set_change_info(9)

✨ set_change_info(9) ✨

okay so bestie, welcome to the set_change_info page from the Kernel API Manual 💅 this one is short and sweet and honestly kinda iconic for it.

---

🎀 NAME 🎀

set_change_info — literally just sets up the change_info4 for a reply, that's the whole gig 🫶

---

🌸 SYNOPSIS 🌸

void set_change_info (struct nfsd4_change_info *cinfo , struct svc_fh
*fhp );

no cap, that's the entire signature 💖

---

🦋 ARGUMENTS 🦋

• cinfo — pointer to the nfsd4_change_info that's gonna get populated, like it's getting its moment ✨
• fhp — pointer to the svc_fh we're pulling from as the source, the main character of this little operation 👑

---

💜 DESCRIPTION 💜

okay so boom: lots of operations in NFSv4 require change_info4 in the reply — it's giving mandatory, non-negotiable, periodt. 💀

This function populates that change_info4 from the info that we (should!) have already collected. yes, the parenthetical "(should!)" is doing a lot of heavy lifting there and honestly same 🙈.

And in the event that we didn't get any pre-attrs? Just zero out both. that's it, that's the fallback, lowkey graceful ngl 🧚
