Good idea, but it could be done a little bit nicer still.

Your new remote_llseek_unlocked is the same as generic_file_llseek
except for the fact that it doesn't take i_mutex. So I'd rather
call it generic_file_llseek_nolock and make generic_file_llseek call
it. While you're at it you could also add some kerneldoc documents
describing them.
