Re: [libvirt] [PATCH v3 6/9] tests: Fix mode_t usage with va_arg()

Clang complains about it: error: second argument to 'va_arg' is of promotable type 'mode_t' (aka 'unsigned short'); this va_arg has undefined behavior because arguments will be promoted to 'int' [-Werror,-Wvarargs] mode = va_arg(ap, mode_t); ^~~~~~ Work around the issue by passing int to va_arg() and casting its return value to mode_t afterwards.
