commit bfa87ac86ce9ff879c5ac49bf09c3999859a8968
Author: Alessandro Carminati <acarmina@redhat.com>
Date:   Tue Nov 22 18:36:48 2022 +0100

    rv/monitors: Move monitor structure in rodata
    
    It makes sense to move the important monitor structure into rodata to
    prevent accidental structure modification.
