Ensure leave one space between state and task name.
w/o patch: runnable tasks: S task PID tree-key switches prio wait ----------------------------------------------------------------- I kworker/0:2 656 87693.884557 8255 120 Sirq/10-ACPI:Ged 829 0.000000 3 49 Sirq/11-ACPI:Ged 830 0.000000 3 49 Sirq/50-arm-smmu 945 0.000000 3 49
with patch: runnable tasks: S task PID tree-key switches prio wait ------------------------------------------------------------------ I kworker/0:2 656 87693.884557 8255 120 S irq/10-ACPI:Ged 829 0.000000 3 49 S irq/11-ACPI:Ged 830 0.000000 3 49 S irq/50-arm-smmu 945 0.000000 3 49
v2: - fix a typo - simpler to add one space before print format
