Message-Id: <20160322.161916.402932899605112194.davem@redhat.com> Date: Tue, 22 Mar 2016 16:19:16 -0400 (EDT) From: David Miller <davem@...hat.com> To: imbrenda@...ux.vnet.ibm.com Cc: labbott@...oraproject.org, netdev@...r.kernel.org, linux-kernel@...r.kernel.org Subject: Re: [PATCH v3 0/2] AF_VSOCK: Shrink the area influenced by prepare_to_wait From: Claudio Imbrenda <imbrenda@...ux.vnet.ibm.com> Date: Tue, 22 Mar 2016 17:05:50 +0100 > This patchset applies on net-next. > > I think I found a problem with the patch submitted by Laura Abbott > ( https://lkml.org/lkml/2016/2/4/711 ): we might miss wakeups. > Since the condition is not checked between the prepare_to_wait and the > schedule(), if a wakeup happens after the condition is checked but before > the sleep happens, and we miss it. ( A description of the problem can be > found here: http://www.makelinux.net/ldd3/chp-6-sect-2 ). > > The first patch reverts the previous broken patch, while the second patch > properly fixes the sleep-while-waiting issue. Series applied, thanks for following up on this.
