[PATCH 3/6] nvme-apple: Never set the opcode in the NVMMU TCB
From: Sven Peter <sven@kernel.org>
Date: 2026-08-06 15:28:47

Sven Peter, Janne Grunau, Keith Busch, Jens Axboe, Christoph Hellwig, Sagi Grimberg, Linus Torvalds
macOS always sets this to zero and the firmware starting with macOS 15
has started to complain about what we're doing here.
