💖 lpfc_mem_free_all 💖

okay so this is a page from the Kernel API Manual and honestly? it's the cleanup-era anthem of the lpfc world. bestie, this is lpfc_mem_free_all(9) — the function that tidies everything up. 🧹✨

✨ NAME ✨

lpfc_mem_free_all — frees all PCI and driver memory. that's it, that's the whole vibe. literally the "closing the tabs" of kernel functions. 🎀

🦋 SYNOPSIS 🦋

void lpfc_mem_free_all (struct lpfc_hba *phba );

no return value, just vibes and deallocation. 💅

🌸 ARGUMENTS 🌸

  • phba — the HBA you want to free memory for. like, hand her the whole card and she'll handle the cleanup. 🫶

🔥 DESCRIPTION 🔥

so what does she actually free? grab a snack, this list ate: 💖

she frees memory from the PCI and driver memory pools, and also the ones used by:

  • lpfc_sg_dma_buf_pool
  • lpfc_mbuf_pool
  • lpfc_hrb_pool

she also frees the kmalloc-backed mempools for LPFC_MBOXQ_t and lpfc_nodelist. and if that wasn't enough — she also frees the VPI bitmask. 👑

like, not me being a whole cleanup icon. she does NOT leave a single loose pointer behind. periodt. 🌈

⭐ RETURN ⭐

None. she gives you nothing back and honestly? that's the point. no return value, no notes. 💀

iykyk, the alloc/free pairs are all matching outfits and they slay. 🦋💜

friendly reminder bestie: this one frees. there's no undo, no take-backs. use her when you're actually done with the memory. 🙈

made with love from ./drivers/scsi/lpfc, dated October 2026 — mwah, go touch some freed memory 💅🎀🍓
