__dynamic_array() of 1 in blktrace?

Hi,
I'm adding a __vstring() to remove all the open coded vsprintf() calls in
events, and came across several of theses in include/trace/events/block:
__dynamic_array( char, cmd, 1)
[..]
__get_str(cmd)[0] = '\0';
Is this to keep backward compatibility with user space?
does it need to be a dynamic array?
