[dm-devel] Re: [PATCH] User-configurable HDIO_GETGEO for dm volumes

<snip>

Just on a side note: I'm currently working on a patch to make disk
geometry information available through sysfs (for all those devices that
provide getgeo) and and extended patch to make it writable through the
same interface by introducing a setgeo function as a companion to getgeo.

Perhaps this'll make some of this easier...
