Isn't len always 0 or -1 ?
int seq_vprintf(struct seq_file *m, const char *f, va_list args)
{
int len;
if (m->count < m->size) {
len = vsnprintf(m->buf + m->count, m->size - m->count, f, args);
if (m->count + len < m->size) {
m->count += len;
return 0;
}
}
seq_set_overflow(m);
return -1;
}

int seq_printf(struct seq_file *m, const char *f, ...)

int ret;
va_list args;
va_start(args, f);
ret = seq_vprintf(m, f, args);
va_end(args);
return ret;
