Now hpp formats are linked using perf_hpp_list_node when hierarchy is
enabled. Use this info to print entries with multiple sort keys in a
single hierarchy properly.
For example, the below example shows using 4 sort keys with 2 levels.
$ perf report --hierarchy -s '{prev_pid,prev_comm},{next_pid,next_comm}' \
--percent-limit 1 -i perf.data.sched
...
# Overhead prev_pid+prev_comm / next_pid+next_comm
