Dear maintainer,

Please consider setting CONFIG_FUNCTION_PROFILER=y for perf-tools'
cachestat and funccount:

# apt-get install --no-install-recommends perf-tools-unstable
...

# cachestat-perf
Counting cache functions... Output every 1 seconds.
/usr/sbin/cachestat-perf: line 115: function_profile_enabled: Permission denied
ERROR: enabling function profiling. Have CONFIG_FUNCTION_PROFILER? Exiting.

# funccount-perf 'vfs*'
Tracing "vfs*"... Ctrl-C to end.
/usr/sbin/funccount-perf: line 114: function_profile_enabled: Permission denied
ERROR: enabling function profiling. Have CONFIG_FUNCTION_PROFILER? Exiting.

Best regards,

Ivan
