✨ __ns_list_release (9) ✨

okay so bestie, welcome to the Kernel API Manual — section 9, we're in the kernel zone now 👑 this one lives in ./security/apparmor/policy_ns.c and it's lowkey iconic.

🌸 NAME 🌸

__ns_list_release — remove all profile namespaces on the list put refs 💅 that's the whole vibe, fr fr.

---

🎀 SYNOPSIS 🎀

void __ns_list_release (struct list_head *head );

no cap, that's the entire signature. short and slay ✨

🦋 ARGUMENTS 🦋

• head — list of profile namespaces — and listen, it's (NOT NULL), so do not come in here with a NULL and expect anything cute to happen 🙈 iykyk.

💜 DESCRIPTION 💜

okay so the requirement, and this is the main character rule of this whole page:

Requires: namespace lock be held 🔒

like, the namespace lock. you hold it. before you call this. periodt. don't be out here releasing namespaces with the lock un-held, that's not the move bestie 😭

what it actually does: removes all profile namespaces on the list, and puts the refs 🫶
