Resizing currently drops consumer lock. This can cause entries to be
reordered, which isn't good in itself. More importantly, consumer can
detect a false ring empty condition and block forever.
Further, nesting of consumer within producer lock is problematic for
tun, since it produces entries in a BH, which causes a lock order
reversal:
To fix, nest producer lock within consumer lock during resize,
and keep consumer lock during the whole swap operation.

This patch is to add support for MSG_MORE on sctp.
It adds force_delay in sctp_datamsg to save MSG_MORE, and sets it after
creating datamsg according to the send flag. sctp_packet_can_append_data
then uses it to decide if the chunks of this msg will be sent at once or
delay it.
Note that unlike [1], this patch saves MSG_MORE in datamsg, instead of
in assoc. As sctp enqueues the chunks first, then dequeue them one by
one. If it's saved in assoc,the current msg's send flag (MSG_MORE) may
affect other chunks' bundling.
Since last patch, sctp flush out queue once assoc state falls into

sctp: check duplicate node before inserting a new transport
sctp has changed to use rhlist for transport rhashtable since commit 7fda702f9315 ("sctp: use new rhlist interface on sctp transport
rhashtable").
But rhltable_insert_key doesn't check the duplicate node when inserting
a node, unlike rhashtable_lookup_insert_key. It may cause duplicate
assoc/transport in rhashtable. like:
client (addr A, B) server (addr X, Y)
connect to X INIT (1)
------------>
connect to Y INIT (2)
------------>
INIT_ACK (1)
<------------
INIT_ACK (2)
<------------
After sending INIT (2), one transport will be created and hashed into
rhashtable. But when receiving INIT_ACK (1) and processing the address
params, another transport will be created and hashed into rhashtable
with the same addr Y and EP as the last transport. This will confuse
the assoc/transport's lookup.
This patch is to fix it by returning err if any duplicate node exists
before inserting it.

sctp: sctp_transport_dst_check should check if transport pmtu is dst mtu
Now when sending a packet, sctp_transport_dst_check will check if dst

updated again, it will not trigger transport->dst/pmtu's update.
It can be reproduced by reducing route's pmtu twice. At the 1st time

sctp_transport_dst_check finds it's obsolete. But at the 2nd time,
cache's mtu is updated, sctp client will never send out any packet,

ibmvnic: Make CRQ interrupt tasklet wait for all capabilities crqs
After sending device capability queries and requests to the vNIC Server,
an interrupt is triggered and the responses are written to the driver's
CRQ response buffer. Since the interrupt can be triggered before all
responses are written and visible to the partition, there is a danger
that the interrupt handler or tasklet can terminate before all responses
are read, resulting in a failure to initialize the device.
To avoid this scenario, when capability commands are sent, we set
a flag that will be checked in the following interrupt tasklet that
will handle the capability responses from the server. Once all
responses have been handled, the flag is disabled; and the tasklet
is allowed to terminate.

sfc: fix filter_id misinterpretation in edge case
On EF10, hardware filter IDs are 13 bits, but in some places we store
32-bit "full filter IDs" in which higher order bits encode the filter
match-priority. This could cause a filter to have a full filter ID of
0xffff, which is also the value EFX_EF10_FILTER_ID_INVALID which we use
in 16-bit "short" filter IDs (without match-priority bits). This would
occur if the hardware filter ID was 0x1fff and the match-priority was 7.
Unfortunately, some code that checks for EFX_EF10_FILTER_ID_INVALID can
be called on full filter IDs, and will WARN_ON if this ever happens.
So, since we have plenty of spare bits in the full filter ID, this patch
shifts the priority bits left one bit when constructing the full filter
IDs, ensuring that the 0x2000 bit of a full filter ID will always be 0
and thus no full filter ID can ever equal EFX_EF10_FILTER_ID_INVALID.
This patch also replaces open-coded full<->short filter ID conversions
with calls to functions, thus keeping the definition of the full filter
ID format in one place.

vmxnet3: prevent building with 64K pages
I got a warning about broken code on ARM64 with 64K pages:
drivers/net/vmxnet3/vmxnet3_drv.c: In function 'vmxnet3_rq_init':
drivers/net/vmxnet3/vmxnet3_drv.c:1679:29: error: large integer implicitly truncated to unsigned type [-Werror=overflow]
rq->buf_info[0][i].len = PAGE_SIZE;
'len' here is a 16-bit integer, so this clearly won't work. I don't think
this driver is used much on anything other than x86, so there is no need
to fix this properly and we can work around it with a Kconfig dependency
to forbid known-broken configurations. qemu in theory supports it on
other architectures too, but presumably only for compatibility with x86
guests that also run on vmware.
CONFIG_PAGE_SIZE_64KB is used on hexagon, mips, sh and tile, the other
symbols are architecture-specific names for the same thing.

In the function rds_ib_xmit_atomic, ib_ring is not allocated

pkt_sched: Remove useless qdisc_stab_lock
The qdisc_stab_lock is used in qdisc_get_stab and qdisc_put_stab.
These two functions are invoked in qdisc_create, qdisc_change, and
qdisc_destroy which run fully under RTNL.
So it already makes sure only one could access the qdisc_stab_list at
the same time. Then it is unnecessary to use qdisc_stab_lock now.

rxrpc: Change module filename to rxrpc.ko
Change module filename from af-rxrpc.ko to rxrpc.ko so as to be consistent
with the other protocol drivers.
Also adjust the documentation to reflect this.
Further, there is no longer a standalone rxkad module, as it has been
merged into the rxrpc core, so get rid of references to that.

rtnl: don't account unused struct ifla_port_vsi in rtnl_port_size
When allocating rtnl dump messages, struct ifla_port_vsi is never dumped,
so we can save header plus payload in rtnl_port_size(). Infact, attribute
IFLA_PORT_VSI_TYPE and struct ifla_port_vsi are not used anywhere in
the kernel. We only need to keep the nla policy should applications in
user space be filling this out. Same NLA_BINARY issue exists as was fixed
in 364d5716a7ad ("rtnetlink: ifla_vf_policy: fix misuses of NLA_BINARY")
and others, but then again IFLA_PORT_VSI_TYPE is not used anywhere, so
just add a comment that it's unused.
