nfs_inode_attrs_cmp(9)

💅 nfs_inode_attrs_cmp(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's a tiny little function from the NFS corner of the kernel and honestly it's giving "short king, big job" 👑 we're literally comparing file attributes, no cap.

---

✨ NAME ✨

nfs_inode_attrs_cmp — compare attributes 🦋

---

🌸 SYNOPSIS 🌸

int nfs_inode_attrs_cmp (const struct nfs_fattr *fattr , const struct
inode *inode );

---

🎀 ARGUMENTS 🎀

• fattr — the attributes, like, the fresh ones you're bringing to the group chat 💌
• inode — pointer to inode, aka the one already cached and living its best life 🫶

---

⭐ DESCRIPTION ⭐

so here's the tea ☕ this function is basically the vibe check between two sets of attributes, and it answers with a number:

• it returns '1' if it thinks the attributes in fattr are more recent than the ones cached in inode — new info just dropped, slay 🔥
• it returns '-1' if the attributes in inode are more recent than the ones in fattr — sorry babe, the cache ate 💀
• and it returns 0 if it's not sure — honest icon behavior, we love a function that admits it doesn't know 🙈

periodt. that's the whole description. no hidden lore, no extra lore in the source, it's literally just those three possible answers 💜
