proc: export statistics for softirq to /proc Export statistics for softirq in /proc/softirqs and /proc/stat. 1. /proc/softirqs Implement /proc/softirqs which shows the number of softirq for each CPU like /proc/interrupts. 2. /proc/stat Add the "softirq" line to /proc/stat. This line shows the number of softirq for all cpu. The first column is the total of all softirqs and each subsequent column is the total for particular softirq.
