libdm: ensure dm_stats_get_area_start includes region offset
The dm_stats_get_area_start (and its '_current_' variant) methods are expected to return the start sector of the area in the containing device.
Make sure the call adds region->start to the returned value. --- libdm/libdm-stats.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-)
