To: "Eric W. Biederman" , Linus Torvalds Cc: linux-kernel@vger.kernel.org, Vasiliy Kulikov , Arkadiusz Miskiewicz , Alexey Dobriyan , Andrew Morton MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Ignoring "uid=#" is the documented behavior from the "mount(8)" man page for procfs. That implies that the proposed patch should be [temporarily] installed. I personally don't care if the option is restored or not. My issue was that this side effect was not documented in any way in the change that occurred -- which affected documented behavior. I mount my /proc file system in a "mount -at nonfs" statement in an initialization script. The "uid" optional parameter was in /etc/fstab. I have removed "uid" in my "at home" copy of the configuration but haven't visited the remote server to fix it there (I can't log in from remote as a result of this issue). --- On Fri, 5/25/12, Linus Torvalds wrote: > If it is *only* uid, maybe we should just expressly ignore it.
