megasas_issue_dcmd_fusion(9)

💖 NAME

okay so this is megasas_issue_dcmd_fusion(9) from the Kernel API Manual, and its whole vibe is literally issuing a MFI Pass thru cmd. That's the assignment. It's giving "hand this command over and let the adapter do its thing" energy. ✨

✨ SYNOPSIS

void megasas_issue_dcmd_fusion (struct megasas_instance *instance ,
struct megasas_cmd *cmd );

it returns void, so no return-value drama here, bestie. 💅

🎀 ARGUMENTS

• instance — the adapter soft state. yep, that whole adapter situation.
• cmd — an mfi cmd pointer. lowercase mfi, keep it cute and keep it exact.
