Yes, the version you attached looks much better, and correct.

Just some minor comments:

Please don't put filenames in top of file comments.  They don't serve
any purpose and easily get out of date.

no lines longer than 80 characters please.

Given that hfsplus never sets i_generation it's superflous.  So just
write the above as

	return hfsplus_iget(sb, ino);

And maybe write a little comment that there is no generation number
in hfsplus.

No need for this comment I think.  All this is pretty well documented
in Documentation/filesystems/Exporting, and all the other filesystems
that just fill out these three methods don't comment on it either.
