Current trace info data lacks the saved cmdline mapping which is needed for pevent to find out the comm of a task. Add this and bump up the version number so that perf can determine its presence when reading. This is mostly corresponding to trace.dat file version 6, but still lacks 4 byte of number of cpus, and 10 bytes of type string - and I think we don't need those anyway.

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.
