Subject: [PATCH 3/7] IB/srp: Rename work request ID labels
Date: Tue, 27 Oct 2015 15:02:11 -0700	[thread overview]
Message-ID: <562FF463.40107@sandisk.com> (raw)
In-Reply-To: <562FF404.7000504-XdAiOPVOjttBDgjK7y7TUQ@public.gmane.org>

Work request IDs in the SRP initiator driver are either a pointer or a
value that is not a valid pointer. Since the local invalidate and fast
registration work requests IDs are not used as masks drop the suffix
"mask" from their name.
