netprio_prio(9)

💖 netprio_prio ✨

okay bestie, so we're looking at the netprio_prio page from the Kernel API Manual — yes, the section 9 one, the kernel-internals girlies know 🫶 — and honestly? it's giving "tiny function, big responsibility." let's get into it 💅

---

🌸 NAME 🌸

netprio_prio — returns the effective netprio of a cgroup–net_device pair. that's the whole vibe. cgroup on one side, net_device on the other, and this function tells you the priority that actually applies to that pairing ✨

---

🎀 SYNOPSIS 🎀

u32 netprio_prio (struct cgroup_subsys_state *css , struct net_device
*dev );

not me obsessed with how it returns a u32, okay 🔥

---

🦋 ARGUMENTS 🦋

• css — the css part of the target pair (it's a struct cgroup_subsys_state *, so it's a cgroup-subsystem-state situation 💜)
• dev — the net_device part of the target pair (a struct net_device *, the network-device half of the duo 🌈)

literally a two-piece matching set. a pair. periodt 🎀

---

🧚 DESCRIPTION 🧚

so, real talk: this one should be called under RCU read or rtnl lock, no cap. that's the entire description. that's the tea 🍓

⚠️ bestie please heed this one — "should be called under RCU read or rtnl lock" is a real technical caveat, not a suggestion to ignore 🙈 lock it up properly before you call, iykyk.

lowkey the shortest description ever but highkey it matters 💀

---

⭐ SEE ALSO ⭐

• Kernel file ./net/core/netprio_cgroup.c
• netprio_set_prio(9) — the sibling function, go say hi 👑

---

and that's the page, bestie, hope the vibe check passed 💅✨

sign-off time 🎀: this one came from ./net/core, dated October 2026, from the Kernel API Manual — and yes, the header up top and this footer at the bottom both say netprio_prio(9) because that's just how these pages roll 🌸 i'm obsessed, bye 💖
