💅 ice_for_each_vf_rcu(9)

okay so bestie, this page lives in the Kernel API Manual, and it's here to explain the ice_for_each_vf_rcu iterator. It's giving “walk the VF entries, but under RCU rules” energy. ✨

---

🌸 NAME 🌸

ice_for_each_vf_rcu — iterate over each VF entry protected by RCU.

---

🎀 SYNOPSIS 🎀

ice_for_each_vf_rcu (pf , bkt , vf );

---

🦋 ARGUMENTS 🦋

• pf — pointer to the PF private structure.
• bkt — bucket index used for iteration.
• vf — pointer to the VF entry currently being processed in the loop.

---

💖 DESCRIPTION 💖

The bkt variable is an unsigned integer iterator used to traverse the VF entries. It is not guaranteed to be the VF's vf_id. Do not assume it is. Use vf->vf_id to get the id number if needed.

The caller is expected to be under rcu_read_lock for the entire loop. Only use this iterator if your loop is short and you can guarantee it does not sleep.

bestie, this is a whole vibe check situation: short loop, no sleeping, rcu_read_lock held the whole time. no cap. 💅

catch you later, bestie 🫶 — this iconic page comes from the source/version vibes of ./drivers/net/ethernet/intel/ice, October 2026, and it's literally ice_for_each_vf_rcu(9) 💖✨
