Parens not needed around the *return* expression.

Please, remove my address pra...@actcom.co.il from your lists! I am
receiving unwanted mail from a lot of people around kernel, ubuntu' debian,
etc - and I have no idea why!
Thank you.
Hello.

...as all you need to do is read the above, which is at the bottom of
every e-mail you receive from LKML.

Hello,
Here is what you need to do:
To unsubscribe from this list [linux-...@vger.kernel.org]: send the
line "unsubscribe linux-kernel" in the body of a message to:
majo...@vger.kernel.org
And similarly, to unsubscribe from e.g linu...@vger.kernel.org you
should send e-mail to: majo...@vger.kernel.org with "unsubscribe
linux-usb" in the body.
Needless to say, you should send the e-mail(s) from the mailbox you
receive unwanted mails on.
