free_lvl2(9)

💅 free_lvl2 💅

okay so welcome to the free_lvl2(9) page, bestie — it lives in the Kernel API Manual and it is a whole little mood. grab a strawberry 🍓 and let's get into it.

---

🌸 NAME 🌸

free_lvl2 — level 2 pble. and yes, the official one-liner says fee level 2 pble, we are simply reporting what the page says, no cap 💀 the typo is part of the lore now, iykyk.

---

✨ SYNOPSIS ✨

void free_lvl2 (struct irdma_hmc_pble_rsrc *pble_rsrc , struct
irdma_pble_alloc *palloc );

that's the whole signature, character for character, don't come for me 🫶 note how it returns void — iconic, gives nothing back, simply vibes ✨

---

🎀 ARGUMENTS 🎀

two args, both little icons in their own way:

• pble_rsrc — the pble resource management situation. that's your resource-management struct, struct irdma_hmc_pble_rsrc *, and it's the first thing you hand over 🌈
• palloc — the level 2 pble allocation. yep, struct irdma_pble_alloc *, that one. level 2. pble. allocation. we love a literal queen 👑

ngl the page does not go into further detail about what happens inside, so neither will i — we do not invent lore on this channel 🙈
