From eddaacc304ba34a28ebba4b0239dd2da072b54bb Mon Sep 17 00:00:00 2001 From: NeilBrown <neilb@suse.com> Date: Thu, 10 Mar 2016 18:06:59 +1100 Subject: [PATCH 244/359] ddf: use 64bit 'size', not 32bit 'info->size' for create. References: bsc#1081910 The 'size' field of mdu_disk_info_t is 32bit and should not be used except for legacy ioctls. super-ddf got this wrong :-( This change makes it possible to create ddf arrays which used more than 2TB of each device.
