netlbl_unlhsh_hash(9)

📦 version 7.3.1, in nixpkgs unstable

💅 netlbl_unlhsh_hash, bestie 💅

okay so real talk, this is netlbl_unlhsh_hash straight out of the Kernel API Manual, section 9 (iykyk, that's the kernel-API girlies section). she's a tiny function with a big job and honestly? she ate. let's get into it 🎀

✨ NAME ✨

netlbl_unlhsh_hash — literally the hashing function for the hash table. that's it. that's her whole personality. no cap. 💖

🦋 SYNOPSIS 🦋

u32 netlbl_unlhsh_hash (int ifindex );

🌸 ARGUMENTS 🌸

  • ifindex — the network interface/device that we're gonna hash. the main character of this whole operation, fr. 🫶

👑 DESCRIPTION 👑

okay so listen up: this is the hashing function for the unlabeled hash table. you hand her a device/interface, she hands you back the bucket number for that device. iconic behavior. it's giving "I know exactly which bucket you belong in" energy. ✨

but — and this is the important part, so eyes on me 🙈 — the caller is responsible for making sure the hash table is protected with either an RCU read lock or the hash table lock. that's on you, not her. don't leave her unprotected, bestie, that's not the vibe. 💀

🔥 SEE ALSO 🔥

🌈 the sign-off 🌈

this lil beauty comes to you from ./net/netlabel and she was stamped with love in October 2026. go forth and hash responsibly, bestie. mwah. 💅💖🎀🌈⭐
