drivers/pcmcia/pcmcia_ioctl.c was scheduled for removal in November 2005 
and has such a printk since 2005.

Without any good reason why it's still in the kernel.

And many users will start whining loudly that the not deprecated driver 
(in this case cifs) has this or that bug not before the patch to finally 
remove the deprecated feature got applied or at least posted.

And will demand that it therefore does not get removed.

How many "WTF happened to smbfs?" emails did you get at RedHat?
