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any purpose and easily get out of date.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 space after the opening brace, please/

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.
