Using Systemtap probing Getting the virtual address location of bytes for every read write operation in Linux
Clash Royale CLAN TAG#URR8PPP

Using Systemtap probing tool I got the way to get total amount of bytes read by a file by probing syscall.read and syscall.read.return function.
syscall.read.return has returnval() which gives the total amount of byte read. I need to get the virtual addresses of the bytes for every read and write operation. How can I achieve this using Systemtap probing tool in linux.

You probably have to dive into ftrace.
