When a process is sent a SIGKILL because it exceeded CPU or RT limits, the cause may not be obvious in userspace -- daemonised processes just get killed, and even foreground process just see a 'Killed' message. The lack of any information on why this might be happening in logs can be confusing to users who are not aware of this mechanism. Add messages which dump the process name and tid in dmesg when a process exceeds its CPU or RT limits (soft and hard) in order to make it clearer to people debugging such issues.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
