💖 _scsih_ir_fastpath(9) 💖

okay bestie, so this one is straight out of the Kernel API Manual (section 9, the kernel-functions girly) — and it's a tiny little function with a giant friend group, iykyk. Let's get into it ✨

🌸 NAME 🌸

_scsih_ir_fastpath — turn on fastpath for IR physdisk

like, it flips the fastpath switch ON for an IR physical disk. that's the whole vibe 🦋

🎀 SYNOPSIS 🎀

int _scsih_ir_fastpath (struct MPT3SAS_ADAPTER *ioc , u16 handle , u8
phys_disk_num );

✨ ARGUMENTS ✨

  • ioc — the per adapter object. it's literally the adapter's main character 💅
  • handle — device handle for physical disk 🫶
  • phys_disk_num — physical disk number. yes bestie, it's the number of the physical disk 😭

🌈 RETURN 🌈

0 for success, else failure. that's it, that's the return value 🎀

🦋 SEE ALSO 🦋

okay so this is the part where I need you to sit down and hydrate, because our girl _scsih_ir_fastpath is extremely well connected. first up, the file this all lives in:

  • Kernel file ./drivers/scsi/mpt3sas/mpt3sas_scsih.c

and now the whole entire group chat 💀 — every single one of these, no skips:

ok that was a LOT of links but we got through it together 🫶 drink some water, you earned it 💅

and that's the page!! 💖 this cutie lives over in ./drivers/scsi/mpt3sas and the docs were stamped October 2026 — so like, save the date bestie, periodt 🌟🎀✨
