Tsirkin) Date: Thu, 16 May 2013 14:10:48 +0300 Subject: [PATCH v2 03/10] frv: uaccess s/might_sleep/might_fault/ In-Reply-To: References: Message-ID: <89d860b7fb23b35e6a15beda9df6ebccf820a2f6.1368702323.git.mst@redhat.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The only reason uaccess routines might sleep is if they fault.
