When dynamic sort key is used it might not show pretty printed output.
This is because the trace output was not set only for the first dynamic
sort key. During hierarchy_insert_entry() it missed to pass the
trace_output to dynamic entries. Also even if it did, only first entry
will have it. Subsequent entries might set it during collapsing stage
but it's not guaranteed.
Before:
$ perf report --hierarchy --stdio -s ptr,bytes_req,gfp_flags -g none
#
# Overhead ptr / bytes_req / gfp_flags
# .............. ..........................................
#
37.50% 0xffff8803f7669400
37.50% 448
37.50% 66080
10.42% 0xffff8803f766be00
8.33% 96
8.33% 66080
2.08% 512
2.08% 67280
After:
#
# Overhead ptr / bytes_req / gfp_flags
# .............. ..........................................
#
