💖 lpfc_rq_buf_free(9) 💖

okay bestie, welcome to the Kernel API Manual — this one's a little function called lpfc_rq_buf_free, and she's literally just here to give a buffer back to the RQ so it can live its best life. 🦋

---

✨ NAME ✨

lpfc_rq_buf_free — free a RQ DMA buffer, no cap 💅

---

🌸 SYNOPSIS 🌸

void lpfc_rq_buf_free (struct lpfc_hba *phba , struct lpfc_dmabuf *mp );

like, that's it. two args, a void, and she's out. 🎀

---

🫶 ARGUMENTS 🫶

• phba — the HBA the buffer is associated with, iykyk 🌈
• mp — the buffer we're freeing, bestie. bye diva 👑

---

💜 DESCRIPTION 💜

so the way this works is: it frees the given DMA buffer the appropriate way, which is giving it back to its associated RQ by reposting it so it can be reused. not me being obsessed with a recycling icon 🧚✨ literally sustainable queen behavior.

• Can be called with or without other locks held — yes she's flexible like that 💅
