The function-trace <-> perf interface is a tad messed up. Where all the other trace <-> perf interfaces use a single trace hook registration and use per-cpu RCU based hlist to iterate the events, function-trace actually needs multiple hook registrations in order to minimize function entry patching when filters are present. The end result is that we iterate events both on the trace hook and on the hlist, which results in reporting events multiple times. Since function-trace cannot use the regular scheme, fix it the other way around, use singleton hlists.

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.
