💖 lpfc_sli4_rb_free — bestie's guide to yeeting a receive buffer 💖

okay so this is lpfc_sli4_rb_free(9) from the Kernel API Manual, and honestly? she's a short queen but she does her job. sit down, grab a strawberry 🍓, and let's get into it.

✨ NAME ✨

lpfc_sli4_rb_free — frees a receive buffer. that's it. that's the whole vibe. 🎀

🌸 SYNOPSIS 🌸

void lpfc_sli4_rb_free (struct lpfc_hba *phba , struct hbq_dmabuf *dmab
);

look at her. two args, no return, no drama. 💅

🦋 ARGUMENTS 🦋

  • phba — the HBA that the buffer was allocated for. like, whose house is this buffer living in? that one. 🏠
  • dmab — the DMA Buffer container that came back from lpfc_sli4_hbq_alloc. it's the little container that could, and now it's gotta go. 😭

🔥 DESCRIPTION 🔥

so what does she actually do? she frees both the container and the DMA-mapped buffers that were handed back by lpfc_sli4_rb_alloc. both of them. no leftovers, no stragglers, we're cleaning everything up. ✨🧹

like, not me being the responsible one who actually deallocates her memory... slay.

⭐ NOTES ⭐

here's the lowkey important bit: you can call this with or without locks held. no cap. she's flexible like that. 🙈

fr fr though, that flexibility is in the original — don't go reading extra meaning into it, that's just what the manpage says. 🫶

💜 RETURN 💜

None. she returns nothing. she's giving main character energy with no receipts. void and unbothered. 👑

and that's the page, bestie! this iconic little number lives in ./drivers/scsi/lpfc, dated October 2026, and she's catalogued as lpfc_sli4_rb_free(9). go free those buffers responsibly, mwah 💋🎀✨
