A term list is turned into a string for debug output and for the str value in the alias. Add a helper to do this based on existing code, but then fix for situations like events being identified. Use strbuf to manage the dynamic memory allocation and remove the 256 byte limit. Use in various places the string of the term list is required. Before: $ sudo perf stat -vv -e inst_retired.any true Using CPUID GenuineIntel-6-8D-1 intel_pt default config: tsc,mtc,mtc_period=3,psb_period=3,pt,branch Attempting to add event pmu 'cpu' with 'inst_retired.any,' that may result in non-fatal errors After aliases, add event pmu 'cpu' with 'event,period,' that may result in non-fatal errors inst_retired.any -> cpu/inst_retired.any/ ...

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
