nfs_revalidate_file_size(9)

🌸 NAME 🌸

okay bestie, this is the nfs_revalidate_file_size(9) page from the Kernel API Manual, and the name is literally:

• nfs_revalidate_file_size — Revalidate the file size. That's it, that's the vibe. 💅

✨ SYNOPSIS ✨

the signature is exactly this, no cap:

int nfs_revalidate_file_size (struct inode *inode , struct file *filp );

🎀 ARGUMENTS 🎀

• inode — pointer to inode struct. Yep, that's the inode pointer.
• filp — pointer to struct file. The file pointer, slay.

💅 DESCRIPTION 💅

It revalidates the file length. Basically it's a wrapper around nfs_revalidate_inode, but with two big-brain exceptions baked in:

• if we may have cached writes, we don't care about the server's idea of what the file length is — like, not even a little.
• if it's O_DIRECT, we shouldn't trust the cache. Periodt.

👀 SEE ALSO 👀

• Kernel file ./fs/nfs/file.c — go peek, iykyk.
