Using:

	gcc (GCC) 4.5.0 20100610 (prerelease)

The following warnings appear:

	fs/readdir.c: In function `filldir64':
	fs/readdir.c:240:15: warning: `dirent' is used uninitialized in this function
	fs/readdir.c: In function `filldir':
	fs/readdir.c:155:15: warning: `dirent' is used uninitialized in this function
	fs/compat.c: In function `compat_filldir64':
	fs/compat.c:1071:11: warning: `dirent' is used uninitialized in this function
	fs/compat.c: In function `compat_filldir':
	fs/compat.c:984:15: warning: `dirent' is used uninitialized in this function

The warnings are related to the use of the NAME_OFFSET() macro.  Luckily,
it appears as though the standard offsetof() macro is what is being
implemented by NAME_OFFSET(), thus we can fix the warning and use a more
standard code construct at the same time.
