Subject: [PATCH] nvme: change nvme_passthru_cmd64 to explicitly mark rsvd
Date: Mon,  4 Nov 2019 22:15:10 -0800	[thread overview]
Message-ID: <20191105061510.22233-1-csm10495@gmail.com> (raw)

Changing nvme_passthru_cmd64 to add a field: rsvd2. This field is an explicit
marker for the padding space added on certain platforms as a result of the
enlargement of the result field from 32 bit to 64 bits in size.
