nsm_reboot_lookup(9)

💅 nsm_reboot_lookup(9) — the nsm_reboot_lookup page, bestie edition 🎀

okay so this is from the Kernel API Manual, and it's literally about matching NLMPROC_SM_NOTIFY arguments to an nsm_handle. stay with me, it's cute 🦋

✨ NAME ✨

nsm_reboot_lookup — match NLMPROC_SM_NOTIFY arguments to an nsm_handle 🫶

---

🌸 SYNOPSIS 🌸

struct nsm_handle * nsm_reboot_lookup (const struct net *net , const
struct lockd_reboot *info );

---

🎀 ARGUMENTS 🎀

• net — the network namespace, bestie 🌐
• info — pointer to the NLMPROC_SM_NOTIFY arguments 💌

---

💖 DESCRIPTION 💖

so the way this works: it returns a matching nsm_handle if one is found in the nsm cache. the returned nsm_handle's reference count is bumped — yes, bumped, iconic behavior 👑

otherwise it returns NULL if some error occurred. that's it, that's the vibe 😭

ngl, NULL here is the "something went wrong" girlie, not the "no match" girlie. the man page says "if some error occurred" and we're not gonna lie to you 💀
