lwq_dequeue(9)

📦 version 7.3.1, in nixpkgs unstable

💅 lwq_dequeue(9) — Kernel API Manual 💅

🌸 NAME 🌸

lwq_dequeue — dequeue first (oldest) entry from lwq. Short name, main character energy, no cap. 💖

✨ SYNOPSIS ✨

lwq_dequeue (q , type , member );

The spaces in that signature are staying, bestie — character for character, periodt. 💅

🎀 ARGUMENTS 🎀

  • q — the queue to dequeue from. The queue in question, the one we're pulling from. 👑
  • type — the type of object to return. Tell it what kind of object you want back. 🦋
  • member — them member in returned object which is an lwq_node. That's the member that is literally an lwq_node. 🔥

🌈 DESCRIPTION 🌈

Okay so lwq_dequeue removes a single object from the lwq and returns it. One (1) object, bestie — not a batch, not the whole queue. 💀

⚠️ This will take a spinlock, so it must always be called in the same context — typically process context. (The page says 'typcially process contet' and honestly same, but the rule is real: same context, always.) 😭
