2.6.11 breaks modules gratuitously

[Greg Stark]

When you guys go on these "make needlessly global code static" kicks you
should maybe consider that even functions that aren't currently used by any
other area of the tree might be useful for module writers.

Instead of just checking which functions are currently used by other parts of
the kernel perhaps you should think about what makes a logical API and stick
to that, even if not all of the functions are currently used.

In the case of net/core/datagram.c, why make skb_copy_datagram private but
leave skb_copy_datagram_iovec global? If the latter is a useful public
function why not the former?

In particular vmware used skb_copy_datagram. So 2.6.11 broke vmware for no
good reason.
