lpfc_release_scsi_buf(9)

💅 lpfc_release_scsi_buf — a Kernel API Manual moment ✨

okay so bestie, welcome to the Kernel API Manual entry for lpfc_release_scsi_buf(9) — yes that (9) means kernel API, iykyk 🎀

---

🌸 NAME 🌸

lpfc_release_scsi_buf — give a scsi buffer back to the hba scsi buf list, no cap 💖

---

✨ SYNOPSIS ✨

void lpfc_release_scsi_buf (struct lpfc_hba *phba , struct lpfc_io_buf
*psb );

like, that's the whole call. void return, two args, iconic 🫶

---

🦋 ARGUMENTS 🦋

• phba — the Hba for which this call is being executed 👑
• psb — the scsi buffer which is being released 🎀

---

🔥 DESCRIPTION 🔥

so what does this routine actually do? bestie, it releases the psb scsi buffer by adding it to the tail of the phba lpfc_scsi_buf_list list. that's it, that's the vibe — buffer goes back on the list, tail end, done 💅✨
