            Bug ID: 97380
           Summary: Add explicit cross-process fencing
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: wayland
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: tomek.bury at gmail.com

Currently Wayland is build around a silent assumption that buffers shared
between client and compositor have implicit cross-process fencing mechanism
built into them. It would be good to have an explicit mechanism in place,
perhaps similar to one found in Android. 

As far as I know, there's already some work done. I'm opening this bug to track
the progress as per our discussion in bug 97353.
