Subject: [PATCH 0/2] inet_diag: Fix old/new inet_diag_req-s structures

The recent changes to inet_diag broke the compilation of tools using kernel headers.

Fix this by doing two sequential renames:

 inet_diag_req -> inet_diag_req_v2
 inet_diag_req_compat -> inet_diag_req

After this the changes in the user-space visible part of the inet_diag.h are
* add the inet_diag_req_v2
* extend the INET_DIAG_ extensions list

The set applies to current net tree.

David, Stephen, I'm a little bit confused with the situation with this header. Can
you please comment on the (quite ancient) commit 73c1f4a0 ([TCPDIAG]: Just rename 
everything to inet_diag) from acme@? This commit did the similar thing with inet_diag
header -- flushed away the old struct and introduced a new one keeping just the binary
compatibility. Why was the breakage of tools caused by this commit considered as 
acceptable?

Thanks,
Pavel
