The inline_node structs are maintained by the new dso->inlines tree. This in turn keeps ownership of the fake symbols and srcline string representing an inline frame. This tree is sorted by address to allow quick lookups. All other entries of the symbol beside the function name are unused for inline frames. The advantage of this approach is that all existing users of the callchain API can now transparently display inlined frames without having to patch their code.

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.
