I am thinking to get number of processes which have been created since the system was booted including kernel and user tasks, not # of current running processes which one can get from procs variable of struct sysinfo. One way is to trace down number of struct task_struct created. I wonder there is a better way for doing that. Thanks, -Hong - Kernelnewbies: Help each other learn about the Linux kernel.
