Subject: [git patch review 5/5] [IPoIB] cleanups: fix comment, remove useless variables
Date: Mon, 31 Oct 2005 22:34:42 +0000 [thread overview]
Message-ID: <1130798082548-b095f02a09987549@cisco.com> (raw)
In-Reply-To: <1130798082548-8e2587fc62785f94@cisco.com>
Minor cleanups: fix a misleading comment, and get rid of attr_mask
variables that are only used to hold constants (just use the constants
directly).
Signed-off-by: Roland Dreier <rolandd@cisco.com>
