        - undo any effect that the dmapi mount event had on this file.  Don't 
carry
          around the dirname, and don't call the event from here.

linux/fs/xfs/linux/xfs_super.c - 1.140
        - If dmapi decided to fail the mount, then it was removing the VFS_DMI
          flag from the vfs--that's not a good thing to do if the filesystem is 
already
          mounted in other places.

linux/fs/namespace.c - 1.4
        - do_add_mount and do_kern_mount do not need to carry around the dirname
          parameter for the dmapi mount event.  Now we use d_path to get the 
dirname.
          Now call the mount event from do_add_mount.
