When having built-in IrDA, we hit the following error:

This is due to the irda_init fix recently added, where we call __exit
routines from an __init one. It is a build failure that I didn't catch
because it doesn't show up when building IrDA as a module. My apologies
for that.
The following patch fixes that failure and is against your net-2.6
tree. I hope it can make it to the merge window, and stable@kernel.org
is CCed on this mail.

This patch extracts common code from irttp_open_tsap() and irttp_dup()

forgetting object initialization in the tsap duplication path in the

Jean II was right: you have to re-charge the final timer when
resending rejected frames. Otherwise it triggers at a wrong time and
can break the currently running communication. Reproducible under

We need to switch to NRM _before_ sending the final packet otherwise
we might hit a race condition where we get the first packet from the
peer while we're still in LAP_XMIT_P.

This patch silences an IRDA_ASSERT in irda_recvmsg_stream, as described in
http://bugzilla.kernel.org/show_bug.cgi?id=7512 irda_disconnect_indication
would set sk->sk_err to ECONNRESET, and a subsequent call to recvmsg
would print an irritating kernel message and return -1.
When a connected socket is closed by the peer, recvmsg should return 0
rather than an error. This patch fixes this.

So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes
on 64bit architectures, allowing us to combine the 4 bytes hole left by the
layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4
64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN...
:-)
Many calculations that previously required that skb->{transport,network,
mac}_header be first converted to a pointer now can be done directly, being
meaningful as offsets or pointers.

This is similar to the skb_reset_network_header(), i.e. at the point we reset
the transport header pointer/offset skb->tail is equal to skb->data.

For the common, open coded 'skb->h.raw = skb->data' operation, so that we can
later turn skb->h.raw into a offset, reducing the size of struct sk_buff in
64bit land while possibly keeping it as a pointer on 32bit.
This one touches just the most simple cases:
skb->h.raw = skb->data;
skb->h.raw = {skb_push|[__]skb_pull}()
The next ones will handle the slightly more "complex" cases.
