💅 rdtgroup_locksetup_user_restore(9) 💅

okay so bestie, this is a Kernel API Manual page, and it's about rdtgroup_locksetup_user_restore — yes, the name is a whole mouthful, iykyk. let's get into it ✨

✨ NAME ✨

rdtgroup_locksetup_user_restore — restore user access to group 🫶

🌸 SYNOPSIS 🌸

int rdtgroup_locksetup_user_restore (struct rdtgroup *rdtgrp );

🎀 ARGUMENTS 🎀

• rdtgrp — the resource group that literally needs its access restored, no cap.

🦋 DESCRIPTION 🦋

So this function restores all file access that was previously removed using rdtgroup_locksetup_user_restrict. That's the whole vibe: undo the restriction and give the files their access back. 💖

🔥 RETURN 🔥

• 0 on success, slay ✅
• <0 on failure 😭

⚠️ okay important: if a failure happens during the restoration of access, an attempt will be made to restrict permissions again, but the state of the mode of these files will be uncertain when a failure occurs. so yeah, failure here is giving chaos — be aware.
