💅 lpfc_scsi_p..._mgmt_cmd_s3(9) 💅

okay so bestie, this page is from the Kernel API Manual (section 9), and the title is literally doing the most with that ... — but we move. 🦋 This one is a very specific little SLI3 task-management helper, and honestly? Niche kernel lore that ate. 💖

🌸 NAME 🌸

lpfc_scsi_prep_task_mgmt_cmd_s3 — convert SLI3 scsi TM cmd to FCP info unit. That's the whole assignment: take an SLI3 scsi task-management command and turn it into the matching FCP information unit. 💅

✨ SYNOPSIS ✨

int lpfc_scsi_prep_task_mgmt_cmd_s3 (struct lpfc_vport *vport , struct
       lpfc_io_buf *lpfc_cmd , u64 lun , u8 task_mgmt_cmd );

🎀 ARGUMENTS 🎀

• vport — the virtual port this call is being executed for. 🫶
• lpfc_cmd — pointer to the lpfc_io_buf data structure. Keep up bestie.
• lun — logical unit number. yes, the lun. iconic.
• task_mgmt_cmd — the SCSI task management command. this is the main character of the whole operation. 👑

🔥 DESCRIPTION 🔥

This routine creates the FCP information unit that corresponds to task_mgmt_cmd, for a device with the SLI-3 interface spec. That's the vibe. SLI-3 specifically — no cap. ✨

Return codes are lowkey a little gremlin-coded, so read carefully:

0 — Error 1 — Success

Not me warning you again: 0 is Error and 1 is Success. Do not flip them. 💀 fr fr.
