Hi,

Will these patches merge into the v7.1-rc series and then back into
perf-tools-next? I don't see them in perf-tools-next:
https://web.git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools-next.git/tree/tools/perf/util/libunwind?h=perf-tools-next

Normally changes like this go from perf-tools-next to perf-tools and
then into Linus' tree.

Thanks,
Ian
