ugh, #linux 5.1.6 and above no longer link with the version of LD on our systems, failing with the error “Invalid absolute R_X86_64_32S relocation: _etext”; one person reported this to LKML in May and then vanished.
So did the project to get vboxsf into the upstream #Linux kernel just totally die in January or did it go somewhere that isn't LKML?
Hans de Goede (the one person working on upstreaming #VirtualBox components) seems to have completely fallen off the Internet...
