Version 1.02.110 -
======================================
Convert dmeventd to use common logging macro system from libdm.
Return -ENOMEM when device registration fails instead of 0 (=success).
Enforce writethrough mode for cleaner policy.
Add support for recognition and deactivation of MD devices to blkdeactivate.
