There is certainly no reason not to report this.
The only real downside to allowing the user to set it is that you don't
get default values by zeroing the layout struct (the default is -1).

A few Ceph ioctls for getting and setting file layout (striping)
parameters, and learning the identity and network address of the OSD a
given region of a file is stored on.
