Merge tag 'perf-core-for-mingo-20160523' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/core improvements from Arnaldo Carvalho de Melo: User visible changes: - Add "srcline_from" and "srcline_to" branch sort keys to 'perf top' and 'perf report' (Andi Kleen) Infrastructure changes: - Make 'perf trace' auto-attach fd->name and ptr->name beautifiers based on the name of syscall arguments, this way new syscalls that have 'const char * (path,pathname,filename)' will use the fd->name beautifier (vfs_getname perf probe, if in place) and the 'fd->name' (vfs_getname or via /proc/PID/fd/) (Arnaldo Carvalho de Melo) - Infrastructure to read from a ring buffer in backward write mode (Wang Nan) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@kernel.org>
