See my dm-cache target in this branch of my tree: https://github.com/jthornber/linux-2.6/tree/thin-dev https://github.com/jthornber/linux-2.6/blob/thin-dev/drivers/md/dm-cache-target.c There's still a lot of work to do on the policy plug-ins, so if you like to get involved that would be great. - Joe _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
