okay bestie, so this page is from the Kernel API Manual (section 9, kernel developer land 🧚) and it's about smack_inode_link, one lil Smack hook that does a vibe check on linking 💖

🌸 SYNOPSIS 🌸

int smack_inode_link (struct dentry *old_dentry , struct inode *dir ,
       struct dentry *new_dentry );

like, that's the whole signature, no cap 🫶

🎀 ARGUMENTS 🎀

  • old_dentry — the existing object, aka the thing that's already here living its main character life 👑
  • dir — unused. literally just sitting there, not doing anything, we love a decorative parameter 💀
  • new_dentry — the new object, the fresh link being made 🦋

✨ DESCRIPTION ✨

okay so here's the tea: it returns 0 if access is permitted ☑️, and an error code otherwise 🙈. that's it, that's the whole function. short and iconic, periodt.
