nfs_verify_change_attribute(9)

💖 NAME 💖

nfs_verify_change_attribute — Detects NFS remote directory changes

okay so you’re on the nfs_verify_change_attribute(9) page of the Kernel API Manual, and honestly? it’s a tiny little helper with main-character energy ✨

🌈 SYNOPSIS 🌈

bool nfs_verify_change_attribute (struct inode *dir , unsigned long verf
);

🎀 ARGUMENTS 🎀

• dir — pointer to parent directory inode. yep, the parent dir’s inode pointer, bestie 🫶
• verf — previously saved change attribute. the change attribute you saved earlier, no cap 💅

🦋 DESCRIPTION 🦋

the whole vibe: it returns "false" if the verifiers doesn’t match the change attribute. (yes, keep that exact energy 😭)

that mismatch would usually indicate that the directory contents have changed on the server, and that any dentries need revalidating. so like… revalidation era is upon us 🔥
