From: Paul Cercueil <paul@xxxxxxxxxxxxxxx>
commit a81fbb8771a3810a58d657763fde610bf2c33286 upstream.
ftw() has been obsolete for about 12 years now.
Committer notes:
Further notes provided by the patch author:
"NOTE: Not runtime-tested, I have no idea what I need to do in perf
to test this. But at least it compiles now with my uClibc-based
toolchain."
I looked at the nftw()/ftw() man page and for the use made with cgroups
in 'perf stat' the end result is equivalent.
Fixes: bb1c15b60b98 ("perf stat: Support regex pattern in --for-each-cgroup")
