Subject: [PATCH AUTOSEL 5.18 37/41] nvme: use struct group for generic command dwords
Date: Thu, 14 Jul 2022 00:22:17 -0400 [thread overview]
Message-ID: <20220714042221.281187-37-sashal@kernel.org> (raw)
In-Reply-To: <20220714042221.281187-1-sashal@kernel.org>
From: Keith Busch <kbusch@kernel.org>
[ Upstream commit 5c629dc9609dc43492a7bc8060cc6120875bf096 ]
This will allow the trace event to know the full size of the data
intended to be copied and silence read overflow checks.
