nfs_inode_attrs_cmp_generic(9)

💅 nfs_inode_attrs_cmp_generic(9) ✨

okay bestie so we're in the Kernel API Manual and this one's a little kernel function called nfs_inode_attrs_cmp_generic. it's giving very niche, very important, very "iykyk" energy and tbh I'm obsessed 🎀

---

🌸 NAME 🌸

nfs_inode_attrs_cmp_generic — compare attributes, fr fr

---

🦋 SYNOPSIS 🦋

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

---

🎀 ARGUMENTS 🎀

• fattr — the attributes, periodt ✨
• inode — pointer to inode 🫶

---

💜 DESCRIPTION 💜

so what this function is doing is, like… attempting to divine whether or not an RPC call reply carrying stale attributes got scheduled after another call carrying updated ones 😭 like it's literally doing detective work on call ordering, main character energy honestly.

also bestie, note the check for wraparound of 'attr_gencount' — don't sleep on that one 🌈

the function returns 1 if it thinks the attributes in fattr are more recent than the ones cached in inode. otherwise it returns the value 0. that's it, that's the whole vibe check 👑
