nfs_post_op_update_inode(9)

💖 nfs_post_op_update_inode(9) 💖

okay so bestie, this is the nfs_post_op_update_inode(9) page from the Kernel API Manual ✨ and it’s literally all about giving the inode attribute cache a little post-operation refresh. no cap, it’s niche but iconic.

🎀 NAME 🎀

nfs_post_op_update_inode — try to update the inode attribute cache

✨ SYNOPSIS ✨

int nfs_post_op_update_inode (struct inode *inode , struct nfs_fattr
*fattr );

🌸 ARGUMENTS 🌸

• inode — pointer to inode
• fattr — updated attributes

🦋 DESCRIPTION 🦋

After an operation that has changed the inode metadata, mark the attribute cache as being invalid, then try to update it. that’s the whole vibe 💅

NB: if the server didn’t return any post op attributes, this function will force the retrieval of attributes before the next NFS request. so pls be careful with it 🙈 Thus it should be used only for operations that are expected to change one or more attributes, to avoid unnecessary NFS requests and trips through nfs_update_inode. fr fr, don’t use it just for fun.

bestie warning: this one is for operations that are expected to change attributes — otherwise you’re just making extra NFS requests for no reason 😭
