Thanks John,

for bringing this to my attention. Yes I will definitely look into this feature and will try to
rework our s390 json files when this seems beneficial.

I did not notice this patch on the linux-perf-users mailing list. Was it there for review?
I do ask this because recently I have nearly no traffic on this list in my reader, so I wonder
if there is something wrong with my mailing list subscription or setup.

Thanks.
