Parenthesis around identifier name in declaration are useless.
This is just "put every macro argument inside parenthesis" practice.

Now "size" must be constant expression, but using comma expression in
constant expression is useless too, therefore [] will guard "size"
expression just as well as ().

Also g++ is somewhat upset about these:

	fs/notify/fanotify/fanotify.h:278:28: warning: unnecessary parentheses in declaration of ‘object_fh’ [-Wparentheses]
	  278 |         struct fanotify_fh (name);
