Add Ronnie to to list. Hello Ronnie, what's the expected behavior from CIFS on atime/noatime? We want to skip the atime related tests on cifs for xfstests just like nfs. But not sure if it's correct. What do you think about it? Thanks. ----- Original Message ----- > From: "Eryu Guan" <guaneryu@gmail.com> > To: "XiaoLi Feng" <xifeng@redhat.com> > Cc: fstests@vger.kernel.org, linux-cifs@vger.kernel.org > Sent: Sunday, May 27, 2018 8:50:58 PM > Subject: Re: [PATCH] common/rc: skip atime related tests on CIFS > > On Tue, May 22, 2018 at 11:23:56AM +0800, Xiaoli Feng wrote: > > From: xiaoli feng <xifeng@redhat.com> > > > > The atime related mount options have no effect on cifs mounts > > now or in the future.

Hi Xiaoli, I think it is fine to skip the atime tests for CIFS. The behaviour of atime/noatime for cifs is basically noatime always. When we read from the server the server will update the atime independently of cisf.ko but then any further reads that we do from cache will never push any updates to the server.
