Subject: [PATCH v3 05/22] Add debug messages for nvme/fcp resource allocation.
Date: Fri, 21 Apr 2017 16:04:49 -0700 [thread overview]
Message-ID: <20170421230506.925-6-jsmart2021@gmail.com> (raw)
In-Reply-To: <20170421230506.925-1-jsmart2021@gmail.com>
From: James Smart <jsmart2021@gmail.com>
The xri resources are split into pools for NVME and FCP IO when NVME is
enabled. There was not message in the log that identified this allocation.
Added debug message to log XRI split.
