Describe the bug

PR_SET_VMA_ANON_NAME is a useful linux feature that allows you to give a name to a mapped memory range. It has been generally available in desktop linux since kernel 5.17. Its support, however, requires enabling CONFIG_ANON_VMA_NAME at kernel compile time, and it is disabled on Raspberry Pi 5 kernel.

It would be nice to see it enabled.

Steps to reproduce the behaviour

sudo modprobe configs
zcat /proc/config.gz | grep CONFIG_ANON_VMA_NAME
# CONFIG_ANON_VMA_NAME is not set
