vfs_fileattr_set(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME

vfs_fileattr_set(9) — change miscellaneous file attributes. bestie, this is the kernel helper that handles those extra lil file attrs for you ✨

🦋 SYNOPSIS

int vfs_fileattr_set (struct mnt_idmap *idmap , struct dentry *dentry ,
struct file_kattr *fa );

🌸 ARGUMENTS

  • idmap — idmap of the mount 🫶
  • dentry — the object to change 💅
  • fa — fileattr pointer, aka your attrs payload 🎀

🔥 DESCRIPTION

okay so here's the vibe: after it verifies permissions, it calls the i_op->fileattr_set callback, if it exists. periodt.

Verifying the attributes means it grabs the current attributes with i_op->fileattr_get. that also lets it initialize attributes that the caller hasn't set to their current values. the inode lock is held thoughout (their spelling, not mine 💀) to prevent racing with another instance. no cap.

⭐ RETURN

0 on success 🎉, or a negative error on failure 😭.
