tracing/ksym_tracer: fix the output of ksym tracer
Fix the output format of ksym tracer, make it properly aligned
Befor patch:
# tracer: ksym_tracer
#
# TASK-PID CPU# Symbol Type Function
# | | | | |
bash 1378 1 ksym_tracer_mutex W mutex_lock+0x11/0x27
bash 1378 1 ksym_filter_head W process_new_ksym_entry+0xd2/0x10c
bash 1378 1 ksym_tracer_mutex W mutex_unlock+0x12/0x1b
cat 1429 0 ksym_tracer_mutex W mutex_lock+0x11/0x27
After patch:
