Yeah, we could, if zfree had moved from tools/perf/util/ to tools/lib/,
which is has not yet.

I thought about doing it now, but when doing some grepping in the kernel
sources I realized that zfree is already taken by... zlib, so I'll leave
this for later, when we figure out how to properly export this, perhaps
renaming it to freez()?
