*	[KERNEL] Refactor to use workqueues and blk-mq only	Simon Rettberg	2022-02-18	1	-4/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Using workqueues frees us from having to manage the lifecycle of three dedicated threads. Discovery (alt server checks) and sending keepalive packets is now done using work on the power efficient system queue. Sending and receiving happens via dedicated work queues with higher priority. blk-mq has also been around for quite a while in the kernel, so switching to it doesn't hurt backwards compatibility. As the code is now refactored to work more as blk-mq is designed, backwards compatibility even improved while at the same time freeing us from an arsenal of macros that were required to make the blk-mq port look and feel like the old implementation. For example, the code now compiles on CentOS 7 with kernel 3.10 without requiring special macros to detect the heavily modified RedHat kernel with all its backported features. A few other design limitations have been rectified along the way, e.g. switching to another server now doesn't internally disconnect from the current one first, which theoretically could lead to a non-working setup, if the new server isn't reachable and then - because of some transient network error - switching back also fails. As the discover-thread was torn down from the disconnect call, the connection would also not repair itself eventually. we now establish the new connection in parallel to the old one, and only if that succeeds do we replace the old one with it, similar to how the automatic alt-server switch already does it.
*	[BUILD] Enable lint targets if lint programs are found	Manuel Bentele	2021-03-11	1	-2/+14
\|
*	[BUILD] Add support in CMake to validate (lint) the source code	Manuel Bentele	2021-03-04	1	-0/+8
\|
*	[BUILD] remove the build requirement for an unused C++ compiler	Manuel Bentele	2020-10-27	1	-1/+2
\| \| \| \| \|	This patch sets the programming languages of each CMake project to C. With this change, CMake does not search for an unused C++ compiler anymore.
*	[BUILD] fix comments and remove useless code fragments in CMake files	Manuel Bentele	2020-10-23	1	-6/+5
\|
*	[BUILD] add CMake targets to build binary and source packages with CPack	Manuel Bentele	2020-10-22	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \|	This patch adds the following CMake targets - package - source to build bundeled packages. Those packages contain either all built binary artifacts or all source files for source code distribution. Both CMake targets are available in Release build configuration.
*	[BUILD] rewrite CMake build system to track changes of source files	Manuel Bentele	2020-10-16	1	-0/+48
	This change restructures the source code directories, separates shared form non-shared application code and adds CMake dependencies. These dependencies allow the tracking of changes and trigger a rebuild of those build targets where changed files are involved. WARNING: Note that the support of the DNBD3_SERVER_AFL build option is not supported yet. Thus, the option should be never turned on.
