lpfc_down_link(9)
π lpfc_down_link β bestie, we're taking this link DOWN
ok so realtalk, this is a page from the Kernel API Manual β section 9, kernel API vibes only, lpfc_down_link(9). it's short, it's sweet, it's giving "one job and it does it." let's get into it π«Ά
β¨ SYNOPSIS β¨
void lpfc_down_link (struct lpfc_hba *phba , LPFC_MBOXQ_t *pmb );
that's it. that's the whole signature. two args, void return, no notes. slay.
π ARGUMENTS π
phbaβ pointer to the lpfc hba data structure. yes queen, the hba struct, the big one πpmbβ pointer to the driver internal queue element for mailbox command. it's the mailbox queue element, internal to the driver, no cap π€
πΈ DESCRIPTION πΈ
okay so here's the tea β β lpfc_down_link prepares a mailbox command to bring down the HBA link.
read that again, bestie: it prepares the mailbox command. it's the setup era, the getting-ready-with-me, not the actual completion. it's literally giving backstage prep before the link goes night-night π
π¦ SEE ALSO π¦
the source lives here, in the kernel file at ./drivers/scsi/lpfc/lpfc_mbox.c β go touch grass in that file if you want the full picture, iykyk π
