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. 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"
