Never saw a warning and never failed to install anything! I checked the
test is there in 208 too and it is.
I even did extract the code and tested it:
needed_symbols='inotify_init signalfd accept4 open_by_handle_at
timerfd_create epoll_create'
for symbol in $needed_symbols; do if ! egrep "^[a-fA-F0-9]+ T
\.?sys_${symbol}$" /proc/kallsyms; then missing_symbol=1;
abort_install=1; break; fi; done
