Sam Ravnborg [Sun, 3 Feb 2008 20:55:49 +0000 (21:55 +0100)]
scsi: fix dependency bug in aic7 Makefile

Building the aic7xxx driver includes the copy
of an .h file from a _shipped file.

In a highly parallel build Ingo saw that the
build sometimes failed (included distcc usage).
It was tracked down to a missing dependency from the .c
source file to the generated .h file.
We started to build the .c file before the
copy (cat) operation of the .h file completed
and we then only got half of the definitions
from the copied .h file.

Add an explicit dependency from the .c files to the
generated .h files so make knows all dependencies and
finsih the build of the .h files before it starts
building the .o files.

Ingo tested this fix and reported:
good news: hundreds of successful kernel builds and no failures
overnight.

[SOCK] proto: Add hashinfo member to struct proto

This way we can remove TCP and DCCP specific versions of

sk->sk_prot->get_port: both v4 and v6 use inet_csk_get_port
sk->sk_prot->hash:     inet_hash is directly used, only v6 need
                       a specific version to deal with mapped sockets
sk->sk_prot->unhash:   both v4 and v6 use inet_hash directly

struct inet_connection_sock_af_ops also gets a new member, bind_conflict, so
that inet_csk_get_port can find the per family routine.

Now only the lookup routines receive as a parameter a struct inet_hashtable.

With this we further reuse code, reducing the difference among INET transport
protocols.

Eventually work has to be done on UDP and SCTP to make them share this
infrastructure and get as a bonus inet_diag interfaces so that iproute can be
used with these protocols.
