nfs_setattr_update_inode(9)

💅 nfs_setattr_update_inode(9) 💅

okay so this is a page from the Kernel API Manual bestie, section 9, and the star of the show is nfs_setattr_update_inode — the little function whose whole personality is "the setattr call happened, now let's make the inode metadata match". ✨

---

🦋 NAME 🦋

nfs_setattr_update_inode — update inode metadata after a setattr call. that's it, that's the vibe. 🎀

---

🌸 SYNOPSIS 🌸

void nfs_setattr_update_inode (struct inode *inode , struct iattr *attr
, struct nfs_fattr *fattr );

she returns void (no little gift back, just vibes) and takes three pointers. slay. 💅

---

✨ ARGUMENTS ✨

• inode — pointer to struct inode. the main character of this whole operation, honestly. 👑
• attr — pointer to struct iattr. the attributes we're working with. 🎀
• fattr — pointer to struct nfs_fattr. the NFS-flavoured attribute buddy. 🦋

---

💀 NOTE 💀

so here's the tea: we do this in the *proc.c in order to ensure that it works for things like exclusive creates too. like, that's the whole reason. no cap. 🔥

genuinely do keep that in mind — the placement in *proc.c isn't random, it's the thing making exclusive creates behave. 🙈
