💖 lpfc_scsi_prep_cmnd_buf_s3(9) 💖

okay so bestie, welcome to the Kernel API Manual page for lpfc_scsi_prep_cmnd_buf_s3(9) ✨ this is literally the SLI-3 IOCB init for the IO, and yes we're gonna get into it.

🌸 NAME 🌸

lpfc_scsi_prep_cmnd_buf_s3 — SLI-3 IOCB init for the IO. that's the name, that's the assignment, no cap 💅

✨ SYNOPSIS ✨

int lpfc_scsi_prep_cmnd_buf_s3 (struct lpfc_vport *vport , struct
       lpfc_io_buf *lpfc_cmd , uint8_t tmo );

🎀 ARGUMENTS 🎀

• vport — pointer to the vport object. your little virtual port bestie, basically 🫶
• lpfc_cmd — the scsi buffer that is going to be prep'ed. yes, prep'ed, we love a verb.
• tmo — timeout value for the IO. it's literally the timeout value for the IO, so it knows how long the vibe gets to cook ⏳

🦋 DESCRIPTION 🦋

based on the data-direction of the command, this initializes the IOCB in the I/O buffer. then it fills in the IOCB fields which are independent of the scsi buffer. that's the whole flow, bestie — data-direction check, IOCB init, independent fields get filled in. slay ✨

RETURNS 0 - SUCCESS, 💅

not me being like “returns 0” and leaving it at that, but that's literally what the page says — 0 is SUCCESS, and the comma is staying because we respect the source 😌
