Proper format is:

	* sysdeps/unix/sysv/linux/bits/fcntl-linux.h
	(F_GETLKP, F_SETLKP, F_SETLKPW): New macros.

> +/*
> + * fd "private" POSIX locks.
> + *
> + * Usually POSIX locks held by a process are released on *any* close and are
> + * not inherited across a fork().

Use GNU style for comments, as you see elsewhere in the file.  Use two
spaces between sentences.  Don't use "function()" when referring to a
function, just the name.

> +#ifndef F_GETLKP
> +# define F_GETLKP	36
> +# define F_SETLKP	37
> +# define F_SETLKPW	38
> +#endif

These need to be protected by #ifdef __USE_GNU.
