It has been determined that the map is for overwrite mode (evlist->overwrite_mmap) or non-overwrite mode (evlist->mmap) when calling perf_evlist__alloc_mmap(). Store the information in struct perf_mmap, which will be used later to simplify the perf_mmap__read*() interfaces.

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.
