Xiao Ni cdf21d08ef Update to latest upstream
After updating to latest upstream, bug2163711 can be fixed.
We don't use rhel only udev rule anymore and we use the
udev rules from upstream. So we don't need to modify our
rhel only udev rule again.

Resolves: bz#2163711

Subject: [PATCH 29/83] Monitor: use devname as char array instead of pointer
Device name wasn't filled properly due to incorrect use of strcpy.
Strcpy was used twice. Firstly to fill devname with "/dev/md/"
and then to add chosen name. First strcpy result was overwritten by
second one (as a result <device_name> instead of "/dev/md/<device_name>"
was assigned). This commit changes this implementation to use snprintf
and devname with fixed size.
