We will soon allocate RX buffers for caching on XDP TX rings.
The rx_ring parameter passed to nfp_net_rx_alloc_one() is not
actually used, remove it.

As Or points out in commit 423b3aecf290 ("net/mlx4: Change ENOTSUPP

Creating a geneve link with 'udpcsum' set results in a creation of link
for which UDP checksum will NOT be computed on outbound packets, as can
be seen below.
11: gen0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN
link/ether c2:85:27:b6:b4:15 brd ff:ff:ff:ff:ff:ff promiscuity 0
geneve id 200 remote 192.168.13.1 dstport 6081 noudpcsum
Similarly, creating a link with 'noudpcsum' set results in a creation
of link for which UDP checksum will be computed on outbound packets.

====================
vxlan: do not error out on disabled IPv6
This patchset fixes a bug with metadata based tunnels when booted with
ipv6.disable=1.

The message "Cannot bind port X, err=Y" creates only confusion. In metadata
based mode, failure of IPv6 socket creation is okay if IPv6 is disabled and
no error message should be printed. But when IPv6 tunnel was requested, such
failure is fatal. The vxlan_socket_create does not know when the error is
harmless and when it's not.
Instead of passing such information down to vxlan_socket_create, remove the
message completely. It's not useful. We propagate the error code up to the
user space and the port number comes from the user space. There's nothing in
the message that the process creating vxlan interface does not know.

When IPv6 is compiled but disabled at runtime, __vxlan_sock_add returns
-EAFNOSUPPORT. For metadata based tunnels, this causes failure of the whole
operation of bringing up the tunnel.
Ignore failure of IPv6 socket creation for metadata based tunnels caused by
IPv6 not being available.

avoid direct access to sk->sk_state when tcp_poll() is called on a socket
using active TCP fastopen with deferred connect. Use local variable
'state', which stores the result of sk_state_load(), like it was done in

While testing a fix [1] in ___pskb_trim(), addressing the WARN_ON_ONCE()
in skb_try_coalesce() reported by Andrey, I found that we had an skb
with skb->sk set but no skb->destructor.
This invalidated heuristic found in commit 158f323b9868 ("net: adjust
skb->truesize in pskb_expand_head()") and in cited patch.
Considering the BUG_ON(skb->sk) we have in skb_orphan(), we should
restrain the temporary setting to a minimal section.

Add fallback code and a WARN_ONCE() call instead of a BUG_ON() in
the ext4_end_bio() function.

Currently ext4_writepages() submits all pages with transaction started.
When no page needs block allocation or extent conversion we can submit
all dirty pages in the inode while holding a single transaction handle
and when device is congested this can take significant amount of time.
Thus ext4_writepages() can block transaction commits for extended
periods of time.
Take for example a simple benchmark simulating PostgreSQL database
(pgioperf in mmtest). The benchmark runs 16 processes doing random reads
from a huge file, one process doing random writes to the huge file, and
one process doing sequential writes to a small files and frequently
running fsync. With unpatched kernel transaction commits take on average
~18s with standard deviation of ~41s, top 5 commit times are:
274.466639s, 126.467347s, 86.992429s, 34.351563s, 31.517653s.
After this patch transaction commits take on average 0.1s with standard
deviation of 0.15s, top 5 commit times are:
0.563792s, 0.519980s, 0.509841s, 0.471700s, 0.469899s
[ Modified so we use an explicit do_map flag instead of relying on
io_end not being allocated, the since io_end->inode is needed for I/O
error handling. -- tytso ]

40GbE Intel Wired LAN Driver Updates 2017-04-30
This series contains updates to i40e and i40evf only.
Jake provides majority of the changes in this series, starting with the
renaming of a flag to avoid confusion. Then renamed a variable to a
more meaningful name to clarify what is actually being done and to
reduce confusion. Amortizes the wait time when initializing or disabling
lots of VFs by using i40e_reset_all_vfs() and
i40e_vsi_stop_rings_no_wait(). Cleaned up a unnecessary delay since
pci_disable_sriov() already has its own delay, so need to add a additional
delay when removing VFs. Avoid using the same name flags for both
vsi->state and pf->state, to make code review easier and assist future
work to use the correct state field when checking bits. Use
DECLARE_BITMAP() to ensure that we always allocate enough space for flags.
Replace hw_disabled_flags with the new _AUTO_DISABLED flags, which are
more readable because we are not setting an *_ENABLED flag to
disable the feature.
Alex corrects a oversight where we were not reprogramming the ports
after a reset, which was causing us to lose all of the receive tunnel
offloads.
Arnd Bergmann moves the declaration of a local variable to avoid a
warning seen on architectures with larger pages about an unused variable.

Since the ECDH key generation takes a different path, it needs to be
tested as well. For this generate the public debug key from the private
debug key and compare both.
This also moves the seeding of the private key into the SMP calling code
to allow for easier re-use of the ECDH key generation helper.

ASoC: Fixes for v4.11
A few last minute fixes for v4.11, the STI fix is relatively large but
driver specific and has been cooking in -next for a little while now:
- A fix from Takashi for some suspend/resume related crashes in the
Intel drivers.
- A fix from Mousumi Jana for issues with incorrectly created
enumeration controls generated from topology files which could cause
problems for userspace.
- Fixes from Arnaud Pouliquen for some crashes due to races with the
interrupt handler in the STI driver.
