But the above commit is for the kernel, scripts/Makefile.extrawarn isn't
included in tools/perf/
This is the one used:
[acme@five perf]$ grep nested-externs tools/scripts/Makefile.include
EXTRA_WARNINGS += -Wnested-externs
[acme@five perf]$
But since you're looking at this, you could consider adding
tools/scripts/Makefile.extrawarn out of tools/scripts/Makefile.include,
etc, to better mimic what is in the kernel sources :-)
Thanks,
