The process_event python hook receives a dict with all perf_sample entries, but the tracepoint specific and trace_unhandled hooks predate the introduction of this dict, and do not receive it. Add the aforementioned dict as an additional argument to the affected handlers. To keep backwards compatibility (and avoid unnecessary work), do not pass the dict if the number of arguments signals that handler version predates this change.

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.
