Subject: [PATCH-v1 01/22] Standardize nvme SGL segment count
Date: Wed, 19 Apr 2017 21:46:20 -0700 [thread overview]
Message-ID: <20170420044641.10657-2-jsmart2021@gmail.com> (raw)
In-Reply-To: <20170420044641.10657-1-jsmart2021@gmail.com>
From: James Smart <jsmart2021@gmail.com>
Standardize default SGL segment count for nvme target and initiator
The driver needs to make them the same for clarity.
