When I use the command cat /proc/<pid>/pagemap, I'm not getting any output. Usually I used to get some binary output but now I am not getting anything.
The output starts coming after an hour or so of entering the command /proc/<pid>/pagemap. I have tried different kernel versions bu the problem still persists.

With kernel processes you don't get output usualls. With user processes try hexdump /proc/pid/pagemap, should show something (zero bytes). Also see unix.stackexchange.com/questions/369185/…
