megasas_make_sgl32(9)

💖 NAME 💖

okay so we're in the Kernel API Manual, and the star of this page is megasas_make_sgl32 — it prepares 32-bit SGL. That's the whole name vibe, bestie. 💅

✨ SYNOPSIS ✨

int megasas_make_sgl32 (struct megasas_instance *instance , struct
       scsi_cmnd *scp , union megasas_sgl *mfi_sgl );

🎀 ARGUMENTS 🎀

• instance — adapter soft state. It's the adapter's state, coming in as a parameter. 🫶
• scp — SCSI command from the mid-layer. The mid-layer sent it, and this function is looking at it. 👑
• mfi_sgl — SGL to be filled in. This one is the target of the fill-in situation, bestie. ✨

🔥 DESCRIPTION 🔥

If it's successful, this function returns the number of SG elements. Otherwise, it returns -1. And yes, the original page literally spells it returnes — typo and all — so don't come for me, I'm just the messenger. 💀

success = the number of SG elements; failure = -1. That's the whole return vibe. No cap. 🫡
