Subject[PATCH v5 1/5] ublk: add opcode offsets for DRV_IN/DRV_OUT
Date
From: Andreas Hindborg <a.hindborg@samsung.com>

Ublk zoned storage support relies on DRV_IN handling for zone report.
Prepare for this change by adding offsets for the DRV_IN/DRV_OUT commands.

Also add parenthesis to existing opcodes for better macro hygiene.
