commit 95d07a3d2d68805d93d36a447436e27c48777939
Author: Poornima G <pgurusid@redhat.com>
Date:   Thu Jan 5 15:36:02 2017 +0530

    ec: Invalidations in disperse volume should not update the stat
    In disperse volume, the file is present across bricks, hence the stat
    from one brick doesn't carry the valid size of the file. Therefore
    the upcall from one brick updating the md-cache results in wrong size
    being updated.
    If the notification is cache invalidation then, indicate md-cache that
    the attributes is invalid.
