nfs_post_op...e_wcc_locked(9)

🌸 NAME 🌸

okay so this is the Kernel API Manual, and the icon we're talking about is nfs_post_op_update_inode_force_wcc_locked — it updates the inode attribute cache. no cap, that's the whole vibe. 💅✨

✨ SYNOPSIS ✨

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

🎀 ARGUMENTS 🎀

• inode — pointer to inode. literally a pointer to the inode, bestie. 🫶
• fattr — updated attributes. the updated attributes, periodt. 💖

🦋 DESCRIPTION 🦋

okay so after an operation that has changed the inode metadata, this function marks the attribute cache as being invalid, then it tries to update it. it also fakes up weak cache consistency data if none exist — yes, fake it till it makes it, but only in the exact way the manpage says. 💀✨

this function is mainly designed to be used by the ->write_done functions. main character energy, fr fr. 👑
