ice_vsi_realloc_stat_arrays(9)

💅 ice_vsi_realloc_stat_arrays — the kernel API manual ✨

okay so bestie, welcome to the ice_vsi_realloc_stat_arrays(9) page — yes that's the whole title, and yes it's a handful to type, we're aware 💀. It lives in the Kernel API Manual and it's one of those little housekeeping gremlins that keeps the ice driver's accounting cute and tidy. Let's get into it 🎀

---

🌸 NAME 🌸

ice_vsi_realloc_stat_arrays — literally just frees unused stat structures or alloc new ones. that's the whole job. it's giving "clean out your closet so the new stuff can move in" energy 🔥

---

✨ SYNOPSIS ✨

int ice_vsi_realloc_stat_arrays (struct ice_vsi *vsi );

so it hands you back an int, and it takes exactly one (1) argument, which we're about to meet 👀 (yes, the spacing is exactly like that, don't come for me, that's just how it's written fr fr)

---

🦋 ARGUMENTS 🦋

• vsi — the VSI pointer 💖 that's it, that's the whole list. one singular pointer, main character energy, no entourage.

ngl bestie, the whole "frees unused stat structures or alloc new ones" thing is literally the entire description on this page — so if you were waiting for a plot twist, this is a short film 😭

and that's the page!! this icon lives over in ./drivers/net/ethernet/intel/ice, and this whole manual moment is dated October 2026, signed off as ice_vsi_realloc_stat_arrays(9) — slay, go free those stat structures, no cap 🧚💜
