The variable 'ret' is set but unused, and this pointed out that
errors from irlmp_connect_response() are not propagated to the
caller.
Note that this is currently academic since irlmp_connect_response()

transforming atomic_inc_return() into atomic_inc() takes away

This is a non-trivial reversion due to intervening commits.

This is removes the use of software prefetching from the regular list
iterators. We don't want it. If you do want to prefetch in some
iterator of yours, go right ahead. Just don't expect the iterator to do
it, since normally the downsides are bigger than the upsides.
It also replaces <linux/prefetch.h> with <linux/const.h>, because the
use of LIST_POISON ends up needing it. <linux/poison.h> is sadly not
self-contained, and including prefetch.h just happened to hide that.
Suggested by David Miller (networking has a lot of regular lists that
are often empty or a single entry, and prefetching is not going to do
anything but add useless instructions).

During the sctp_close() call, we do not use rcu primitives to
destroy the address list attached to the endpoint. At the same
time, we do the removal of addresses from this list before
attempting to remove the socket from the port hash
As a result, it is possible for another process to find the socket
in the port hash that is in the process of being closed. It then
proceeds to traverse the address list to find the conflict, only
to have that address list suddenly disappear without rcu() critical
section.
Fix issue by closing address list removal inside RCU critical
section.
Race can result in a kernel crash with general protection fault or
kernel NULL pointer dereference:

They not only increase the code footprint, they actually make things
slower rather than faster. On internationally acclaimed benchmarks
("make -j16" on an already fully built kernel source tree) the hlist
prefetching slows down the build by up to 1%.
(Almost all of it comes from hlist_for_each_entry_rcu() as used by
avc_has_perm_noaudit(), which is very hot due to all the pathname
lookups to see if there is anything to do).
The cause seems to be two-fold:
- on at least some Intel cores, prefetch(NULL) ends up with some
microarchitectural stall due to the TLB miss that it incurs. The
hlist case triggers this very commonly, since the NULL pointer is the
last entry in the list.
- the prefetch appears to cause more D$ activity, probably because it
prefetches hash list entries that are never actually used (because we
ended the search early due to a hit).
Regardless, the numbers clearly say that the implicit prefetching is
simply a bad idea. If some _particular_ user of the hlist iterators
wants to prefetch the next list entry, they can do so themselves
explicitly, rather than depend on all list iterators doing so
implicitly.

ipv6 has per device ICMP SNMP counters, taking too much space because
they use percpu storage.
needed size per device is :
(512+4)*sizeof(long)*number_of_possible_cpus*2
On a 32bit kernel, 16 possible cpus, this wastes more than 64kbytes of
memory per ipv6 enabled network device, taken in vmalloc pool.
Since ICMP messages are rare, just use shared counters (atomic_long_t)
Per network space ICMP counters are still using percpu memory, we might
also convert them to shared counters in a future patch.
