    kernel - Fix fstatfs() and fstatvfs() when called from a null-mounted chroot()
    
    * These funtions were using the wrong starting mount pointer when calling
      cache_fullpath().  They were using the mount pointer for the open file's
      vnode instead of the overlay (null) mount pointer.
    
      This caused cache_fullpath() to believe the fd represented a file outside
      the chroot and return an error.
