Current perf diff result is somewhat confusing since it sometimes hide
small result and sometimes there's no result. So do not hide small
result (less than 0.01%) and print "N/A" if baseline is not
recorded (for ratio and wdiff only). Blank means the baseline is
available but its pairs are not.
Before:
# Baseline Delta Shared Object Symbol
# ........ ....... ................. .........................

...
0.01% -0.01% [kernel.kallsyms] [k] native_write_msr_safe
0.01% [kernel.kallsyms] [k] scheduler_tick
0.01% [kernel.kallsyms] [k] native_read_msr_safe
0.00% [kernel.kallsyms] [k] __rcu_read_unlock
[kernel.kallsyms] [k] _raw_spin_lock
+0.01% [kernel.kallsyms] [k] apic_timer_interrupt
[kernel.kallsyms] [k] read_tsc
After:
