From Milian's cover letter: (Milian Wolff) This series of patches completely reworks the way inline frames are handled. Instead of querying for the inline nodes on-demand in the individual tools, we now create proper callchain nodes for inlined frames. The advantages this approach brings are numerous: - Less duplicated code in the individual browser - Aggregated cost for inlined frames for the --children top-down list - Various bug fixes that arose from querying for a srcline/symbol based on the IP of a sample, which will always point to the last inlined frame instead of the corresponding non-inlined frame - Overall much better support for visualizing cost for heavily-inlined C++ code, which simply was confusing and unreliably before - srcline honors the global setting as to whether full paths or basenames should be shown - Caches for inlined frames and srcline information, which allow us to enable inline frame handling by default Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEELb9bqkb7Te0zijNb1lAW81NSqkAFAlnwsBYACgkQ1lAW81NS qkBQrxAAkARBYgZS5y2WFSDB8zIvXHBPiMmTDNwpgAIUo66YMAI9+y18VoTGBwju kTbD1VhLQAg1DRODuGjwnT2lKLDkl2kYhP5hwzFZYk7L8/F0jBtrPNI3uM3kOgvm zfmMHpKMWCdRU1gcLqmhW3gUs5ySHj7iZuZWWTlyrmTJoBzpQFRnGi89gNds5NkC 0nY0HU099HnTgBcAkidExg5RYKhFjevYnisuBW4Ob7g34WMYgL44cVepnBzuBZdn uKYFFUsnd+aL4Spq6jr+W31XVv61xUKttaSKT7PUrWiDGzRdpTQZLXwzd7cyJShF e0TGvTtqt1xSpTU9YCZvAqfs0K5gkp0e9OddYB/P1Wne1oj7tWAa4kKFdccYFMY1 +rbPMK0A/ms37QMx3m+/zJ+07dxuu94W/MI6k+KW+Al10QnKQSaAzLe7XxZU4p8y TA7KOrrZI/KYOvTyIHpeeI1LFHnn4OZy+LnkoxxH71fmCphsUsGvNIhzID1ntffK I/RLhpe1+9425NhViZlCoD4+vIMf9CCpJYhGNQZ6ndK+ESacuWUa4DTRJYUnF5xZ ducZefpm7XCTwnvkkvNN3JwmeBI0H9ePaepvLjLJP11RzZyE9fgcRdQIcPBNC76+ a2NEkq/ean+pEFiz6S5vYrz0DSw5FTfJbfCVrVXQkYQVZcCU7F8= =IEC2 -----END PGP SIGNATURE----- Merge tag 'perf-core-for-mingo-4.15-20171025' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core Pull perf/core inline improvements from Arnaldo Carvalho de Melo: From Milian's cover letter: (Milian Wolff) "This series of patches completely reworks the way inline frames are handled.

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.
