I tried to apply but I'm afraid that for 32-bit userspace this gives me: daemon/main.c: In function 'increase_fd_limit': daemon/main.c:89:10: error: format '%lu' expects argument of type 'long unsigned int', but argument 3 has type 'rlim_t' [-Werror=format] daemon/main.c:89:10: error: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'rlim_t' [-Werror=format] daemon/main.c:89:10: error: format '%lu' expects argument of type 'long unsigned int', but argument 5 has type 'rlim_t' [-Werror=format] daemon/main.c:89:10: error: format '%lu' expects argument of type 'long unsigned int', but argument 6 has type 'rlim_t' [-Werror=format] I've no idea how one is formally supposed to print and rlim_r.
