Source code changes of the file "drbd/drbd_main.c" between
drbd-9.1.8.tar.gz and drbd-9.1.9.tar.gz

About: DRBD (9.x) is a block device which is designed to build high availability clusters. This is done by mirroring a whole block device via (a dedicated) network. You could see it as a "network RAID-1". The driver code got integrated into the vanilla Linux kernel.
