🌸 NAME 🌸

tomoyo_update_path_acl — update the "struct tomoyo_path_acl" list. that's it. that's the whole job. she updates the list. periodt 💅

✨ SYNOPSIS ✨

int tomoyo_update_path_acl (const u16 perm , struct tomoyo_acl_param *param );

literally just look at her. two args, one return. clean. minimal. main character energy 🔥

🦋 ARGUMENTS 🦋

  • perm — the permission. it's a const u16, she's little but she matters 💖
  • param — a pointer to "struct tomoyo_acl_param". yes the quotes are part of the original vibe, don't come for me 🙈

👑 DESCRIPTION 👑

so here's the tea 🍓 she returns 0 on success, and a negative value otherwise. that's the whole contract, no cap.

⚠️ okay important one: the caller holds tomoyo_read_lock. that's not optional, that's not a suggestion, that's the rule. the caller is holding it. don't be weird about it 💀
