Write a program using c language to find the page fault for individual processes, group of processes and the system as a whole using the following system call int sys_pgfltstats(pid_t pid,int flag,pf_info_struct *info)
where pf_info_struct should contain fields of
1. total number of major page faults
2. total number of major page faults
3. number of processes included in these counts
If pid is:
* -1: then return total count statistics for all processes in the system.
* positive then look at the flag field and do the following:
1. flag is PGFLTSTAT_PROC: then return count statistics for the single process with the matching pid
2. flag is PGFLTSTAT_OWNER: then return the total count statistics for all process in the system with the same owner as the specified pid.
