Subject: proc-export-statistics-for-softirq-to-proc
From: Keika Kobayashi <kobayashi.kk@xxxxxxxxxxxxxx>
Sorry for my late response....
I replaced to softirq_to_name[] which is already in kernel/softirq.c.
Regarding /proc/softirq,
Ingo pointed out the difference from /proc/interrupts style.
# Thank you!
So, I inserted colon between softirq name and its statistics.
Here is update patch.
