switchdev_po..._is_deferred(9)

💅 switchdev_port_obj_act_is_deferred — is that object action still pending, bestie?

okay so first things first: this page is a kernel API manual page, section 9, and the function we're obsessing over is switchdev_port_obj_act_is_deferred. Yes the header truncates it to switchdev_po..._is_deferred(9) — that's just the man page being dramatic and running out of room, the real name is the long one. 🎀

✨ NAME ✨

switchdev_port_obj_act_is_deferred — literally just: is this object action pending? that's the whole vibe check. 💖

---

🌸 SYNOPSIS 🌸

bool switchdev_port_obj_act_is_deferred (struct net_device *dev , enum
       switchdev_notifier_type nt , const struct switchdev_obj *obj );

it returns a bool, bestie. no mystery there. 🦋

---

🎀 ARGUMENTS 🎀

• dev — the port device. like, the actual net device we're asking about. 🫶
• nt — the type of action; it's add or delete. pick your fighter. ⭐
• obj — the object to test. this is the thing we're checking on. 👑

---

💅 DESCRIPTION 💅

Returns true if a deferred item is pending — which is equivalent to the action nt on an object obj. so basically: "is this exact thing still queued up?"

🚨 ok important one, no cap: rtnl_lock must be held. this is not a suggestion, this is the law. hold the lock before you call this. periodt. 🔥

and that's the whole page, bestie 💜 — huge shoutout to ./net/switchdev for hosting, the date stamp says October 2026, and the man page source/version footer is out here still calling it switchdev_po..._is_deferred(9) like it didn't just explain the entire function. iconic, honestly. 🙈✨
