lpfc_bsg_is...box_ext_cmpl(9)

💅 lpfc_bsg_issue_read_mbox_ext_cmpl — a Kernel API Manual moment 🎀

okay bestie, so this is a page straight out of the Kernel API Manual, and the star of the show has a name so long the header had to abbreviate it: lpfc_bsg_is...box_ext_cmpl(9). iconic behavior tbh. let's get into it 🦋

---

✨ NAME ✨

lpfc_bsg_issue_read_mbox_ext_cmpl — the compl handler for multi-buffer read mbox 💖

(yes, "compl" = completion, she's just vibing with the shorthand, iykyk)

---

🌸 SYNOPSIS 🌸

void lpfc_bsg_issue_read_mbox_ext_cmpl (struct lpfc_hba *phba ,
LPFC_MBOXQ_t *pmboxq );

like, that's the whole signature. no return value, she returns void, she's mysterious like that 💅

---

🎀 ARGUMENTS 🎀

• phba — pointer to the HBA context object. literally the context bestie, the whole vibe of the host bus adapter 🫶
• pmboxq — pointer to the mailbox command. the actual mbox in question, the main character 👑

---

💜 DESCRIPTION 💜

so what does she do? she's the completion handler function for mailbox read commands with multiple external buffers. that's it, that's the whole job. when a multi-buffer read mbox finishes, this is the girl who gets the callback. no cap, she handles the completion. ✨🔥

lowkey that's a lot of friends but she's got range, okay? go read ./drivers/scsi/lpfc/lpfc_bsg.c and tell them I said hi 🍓
