Subject: [patch 2/6] infiniband: remove dependency on __GFP_NOFAIL
Date: Tue, 20 Jul 2010 19:44:56 -0700 (PDT)	[thread overview]
Message-ID: <alpine.DEB.2.00.1007201938570.8728@chino.kir.corp.google.com> (raw)
In-Reply-To: <alpine.DEB.2.00.1007201936210.8728@chino.kir.corp.google.com>

The alloc_skb() in various allocations are failable, so remove
__GFP_NOFAIL from their masks.
