lpfc_sli_prep_dev_for_reset(9)

💅 NAME 💅

So like, this is lpfc_sli_prep_dev_for_reset(9) from the Kernel API Manual, and it's literally here to prepare an SLI3 device for a pci slot reset. Bestie, it's giving "last-minute cleanup before the reset chaos." 💖

✨ SYNOPSIS ✨

void lpfc_sli_prep_dev_for_reset (struct lpfc_hba *phba );

🎀 ARGUMENTS 🎀

• phba — pointer to lpfc hba data structure. That's the one and only argument, and yes, she's important. 🫶

🦋 DESCRIPTION 🦋

Okay so this routine gets called to prepare the SLI3 device for PCI slot reset. Iconic behavior actually: it disables the device interrupt and pci device, and aborts the internal FCP pending I/Os. No cap, that's the whole vibe. ✨
