I'm using this system call in an application and noticed that's marked
as deprecated now.
My application collects all kind of information from crashing programs.
It's installed in /proc/sys/kernel/core_pattern.

If program X is crashing it executes get_robust_list(X) to get the
address of the robust list
and reads the list from /proc/X/mem.

Is there another way to get the robust list from another program (by it's pid)?
