Anonymous VMA name support

configname: CONFIG_ANON_VMA_NAME

Linux Kernel Configuration

In linux kernel since version 5.2 (release Date: 2019-07-07)  
Allow naming anonymous virtual memory areas.

This feature allows assigning names to virtual memory areas. Assigned
names can be later retrieved from /proc/pid/maps and /proc/pid/smaps
and help identifying individual anonymous memory areas.
Assigning a name to anonymous virtual memory area might prevent that
area from being merged with adjacent virtual memory areas due to the
difference in their name.
