Hi Namhyung,

If I do:

# perf record --call dwarf -p 2519 -e syscalls:sys_enter_open

And then run plain 'perf report' I get this on the TUI, perfect:

Samples: 1 of event 'syscalls:sys_enter_open', Event count (approx.): 1
Children Self Trace output
+ 100.00% 100.00% filename: 0x7efe0cc9a96a, flags: 0x00000000, mode: 0x7fffa3da07f0

But if I use 'perf report --no-children' I get it chopped off at the
start of the first tp arg value:

Samples: 1 of event 'syscalls:sys_enter_open', Event count (approx.): 1
Overhead Trace output
+ 100.00% filename: 0x

:-\
