ufshcd_mcq_nullify_sqe(9)

✨ NAME ✨

okay so bestie, welcome to the Kernel API Manual page for ufshcd_mcq_nullify_sqe(9). This one is literally about nullifying the submission queue entry: write the sqe's Command Type to 0xF. The host controller will not fetch any sqe with Command Type = 0xF. That's the whole vibe — no cap. 💅

🫶 SYNOPSIS 🫶

void ufshcd_mcq_nullify_sqe (struct utp_transfer_req_desc *utrd );

💖 ARGUMENTS 💖

• utrd — the UTP Transfer Request Descriptor to be nullified. That's the one getting the 0xF treatment, bestie. ✨
