mega_get_ldrv_num(9)

💖 NAME 💖

mega_get_ldrv_num — bestie… the description slot is literally empty. Nothing. Nada. The manpage said "here's the name" and then just vibed 🫶 so that's what we're working with.

✨ SYNOPSIS ✨

int mega_get_ldrv_num (adapter_t *adapter , struct scsi_cmnd *cmd , int channel );

🎀 ARGUMENTS 🎀

• adapter — pointer to our soft state, aka the whole personality of the adapter, handed to you on a platter 💅
• cmd — the scsi mid layer command, it's giving "I'm the actual request bestie" ✨
• channel — which channel on the controller we're talking about, no cap 🌸

🦋 DESCRIPTION 🦋

okay so here's the whole gig: this function calculates the logical drive number based on the information inside the scsi command 💫 plus the channel number. That's it, that's the function. Numbers in, logical drive number out, slay 👑
