lpfc_get_scsi_buf(9)

💅 lpfc_get_scsi_buf(9) — like, the Kernel API Manual page you actually wanna read ✨

okay bestie, settle in, we're in the Kernel API Manual and today's main character is lpfc_get_scsi_buf(9) 🎀

---

✨ NAME ✨

lpfc_get_scsi_buf — grab a scsi buffer from the lpfc_scsi_buf_list of the HBA 🦋

---

✨ SYNOPSIS ✨

struct lpfc_io_buf* lpfc_get_scsi_buf (struct lpfc_hba *phba , struct
lpfc_nodelist *ndlp , struct scsi_cmnd *cmnd );

like yes, that's the whole vibe 💅

---

✨ ARGUMENTS ✨

• phba — the HBA we're doing this call for, that's it, that's the whole thing 🫶
• ndlp — a pointer to a node-list data structure 👑
• cmnd — a pointer to a scsi_cmnd data structure 🌸

---

✨ DESCRIPTION ✨

so what does this actually do? okay so — this routine takes a scsi buffer off the head of the phba lpfc_scsi_buf_list list and hands it right back to whoever called. literally snatching it from the front of the line, no cap 😭

Return codes, and this part matters, don't skip it:

• NULL — error 💀
• pointer to lpfc_scsi_buf — success 🔥

ngl bestie, keep an eye on that NULL — it's giving "something went wrong" energy and you don't wanna ignore it 🙈
