From: Jeff Mahoney <jeffm@suse.com>
Subject: grub2: use stat instead of udevadm for partition lookup
References: bnc#883635
sysfs_partition_path calls udevadm to resolve the sysfs path for
a block device. That can be accomplished by stating the device node
and using the major/minor to follow the symlinks in /sys/dev/block/.
This cuts the execution time of grub2-mkconfig from 10s to 2s on
my system.
