Source code changes of the file "drbd/drbd-kernel-compat/cocci_cache/38ce2fe160c155a5573c5ede9601abee/compat.patch" between
drbd-9.1.10.tar.gz and drbd-9.1.11.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.
