💅 ksmbd_conn_put(9) — the kernel API manual, bestie edition ✨

okay so like, welcome to the glow-up of ksmbd_conn_put(9) 🎀 yes that's the kernel API manual page, and yes it's lowkey iconic. we're dropping references today. stay with me.

---

✨ NAME ✨

ksmbd_conn_put — drop a reference, and if that was literally the last one, queue the release onto ksmbd_conn_wq so it runs from process context. periodt. 💅

---

✨ SYNOPSIS ✨

void ksmbd_conn_put (struct ksmbd_conn *conn );

---

✨ ARGUMENTS ✨

• conn — the connection instance you're putting a reference to 🫶 like, this is the one you're letting go of.

---

✨ DESCRIPTION ✨

bestie listen, this is the good part 🔥 you can call this from any context — and I mean any — including RCU softirq callbacks and non-sleeping locks. the way that it just handles it?? because the actual release is deferred to the workqueue, so nobody's out here sleeping in a softirq. no cap. 😭

ksmbd_conn_wq is created in ksmbd_server_init before any conn can even be allocated, and it's destroyed in ksmbd_server_exit after rcu_barrier — so it is always non-NULL while a conn reference is held. it's giving guaranteed-valid-pointer main character energy 👑✨

fr fr though, that ordering is the whole vibe check of this function — the workqueue outlives every possible conn, so the deferred release always has somewhere safe to land 🦋
