tools lib traceeveent: Allow for negative numbers in print format
It was reported that "%-8s" does not parse well when used in the printk
format. The '-' is what is throwing it off. Allow that to be included.
Reporter note:
Example before:
transhuge-stres-10730 [004] 5897.713989: mm_compaction_finished: node=0
zone=>-<8s order=-2119871790 ret=
Example after:
transhuge-stres-4235 [000] 453.149280: mm_compaction_finished: node=0
zone=ffffffff81815d7a order=9 ret=
(I will send patches to fix the string handling in the tracepoints so
it's on par with in-kernel printing via trace_pipe:)
transhuge-stres-10921 [007] ...1 6307.140205: mm_compaction_finished: node=0
zone=Normal order=9 ret=partial
