okay so bestie, welcome to the Kernel API Manual entry for netprio_set_prio(9) — yes the manual name is literally baked into the title, that's just how kernel docs roll, iykyk 🫶

✨ NAME ✨

netprio_set_prio — set netprio on a cgroup-net_device pair 🎀

like, you've got a cgroup and you've got a net_device, and this function is the matchmaker that sets the netprio on the pair of them. slay.

---

🌸 SYNOPSIS 🌸

int netprio_set_prio (struct cgroup_subsys_state *css , struct
       net_device *dev , u32 prio );

three args, returns an int, that's the whole vibe 🔥

---

🦋 ARGUMENTS 🦋

• css — the css part of the target pair, bestie 💖
• dev — the net_device part of the target pair 🌈
• prio — the prio to set, periodt ✨

---

👑 DESCRIPTION 👑

Set netprio to prio on the css-dev pair. simple as that 💅

⚠️ okay but fr fr listen to this part: it should be called under rtnl lock, and it may fail under memory pressure for non-zero prio. so like, don't just call it wherever, and don't be shocked if a non-zero prio ghosts you when memory is struggling 😭 not its fault, it's just the vibes.
