nfs_inode_a...mp_monotonic(9)

🎀 NAME 🎀

nfs_inode_attrs_cmp_monotonic — compare attributes. Okay bestie, this is the Kernel API Manual page for that exact function, and we're about to vibe-check some NFS attributes 💅✨

✨ SYNOPSIS ✨

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

💖 ARGUMENTS 💖

• fattr — attributes 🎀
• inode — pointer to inode 🦋

🔥 DESCRIPTION 🔥

Okay so picture this: the function is literally trying to divine whether or not an RPC call reply carrying stale attributes got scheduled after another call carrying updated ones 👀

The whole vibe rests on one assumption: we assume that the server observes monotonic semantics for the change attribute. So a larger value means that the attributes in fattr are more recent — and in that case the function returns the value '1' 🎉. A return value of '0' indicates no measurable change. A return value of '-1' means that the attributes in inode are more recent. That's the whole ranking, no cap 💯
