devlink_try_get(9)

✨ devlink_try_get(9) ✨

okay so bestie, we're diving into the kernel API manual (devlink_try_get(9)) and honestly? this one is short but it's giving "small but mighty" energy. let's get into it 💅

---

🌸 NAME 🌸

devlink_try_get — try to obtain a reference on a devlink instance

like, try. that word is doing a lot of work here, and we respect it 🫶

---

🎀 SYNOPSIS 🎀

struct devlink * devlink_try_get (struct devlink *devlink );

---

🦋 ARGUMENTS 🦋

• devlink — the instance you're trying to get a reference on. that's the one, bestie 🎯

---

💖 DESCRIPTION 💖

So here's the tea: devlink_try_get obtains a reference on a devlink instance. simple enough, right?

But wait — and this is the part you cannot skip, babes — a reference on a devlink instance only implies that it's safe to take the instance lock. that's it. that's the whole promise. ✋

It does not imply that the instance is registered. like, at all. so if you need to know whether it's actually registered, you gotta use devl_is_registered — and crucially, you call that after taking the instance lock to check the registration status. order matters, no cap. 🔥

⚠️ do not assume a successful reference means "registered". it does not. take the lock, then check with devl_is_registered. periodt. 💀
