"Items of note:

worked fine with NVMe over Fabrics and mlx5 adapters. That broke in

If the driver receives a TX CQE with status as 0x1 or 0x9 or 0xb,
the completion indexes should not be used. The driver must stop
consuming CQEs from this TXQ/CQ. The TXQ from this point on-wards
to be in a bad state. Driver should destroy and recreate the TXQ.
0x1: LANCER_TX_COMP_LSO_ERR
0x9 LANCER_TX_COMP_SGE_ERR
0xb: LANCER_TX_COMP_PARITY_ERR
Reset the adapter if driver sees this error in TX completion. Also

net: erspan fixes
The first patch fixes erspan metadata extraction issue from packet
header due to commit d350a82302 ("net: erspan: create erspan metadata
uapi header"). The commit moves the erspan 'version' in
'struct erspan_metadata' in front of 'struct erspan_md2' for later
extensibility, but breaks the existing metadata extraction code due
to extra 4-byte size 'version'. The second patch fixes the case where
tunnel device receives an erspan packet with different tunnel metadata
(ex: version, index, hwid, direction), existing code overwrites the
tunnel device's erspan configuration. The third patch fixes the bpf
tests due to the above patches.

The commit c69de58ba8 ("net: erspan: use bitfield instead of

commit d350a82302 ("net: erspan: create erspan metadata uapi header")
creates a uapi header file. The above two commit breaks the current
erspan test. This patch fixes it by adapting the above two changes.

The problem is that the htnode is freed before the linked knodes and the
latter will try to access the first at u32_destroy_key() time.
This change addresses the issue using the htnode refcnt to guarantee
the correct free order. While at it also add a RCU annotation,
to keep sparse happy.
v1 -> v2: use rtnl_derefence() instead of RCU read locks
v2 -> v3:
- don't check refcnt in u32_destroy_hnode()
- cleaned-up u32_destroy() implementation
- cleaned-up code comment
v3 -> v4:
- dropped unneeded comment

Moving the qrwlock struct definition into a header file introduced
a subtle bug on all little-endian machines, where some files in some
configurations would see the fields in an incorrect order. This was
found by building with an LTO enabled compiler that warns every time we
try to link together files with incompatible data structures.
A second patch changes linux/kconfig.h to always define the symbols,
but this seems to be the root cause of most of the issues, so I'd suggest
we do both.
On a current linux-next kernel, I verified that this header is
responsible for all type mismatches as a result from the endianess
confusion.

Fix dst reference count leak in sctp_v4_get_dst() introduced in commit
410f03831 ("sctp: add routing output fallback"):
When walking the address_list, successive ip_route_output_key() calls
may return the same rt->dst with the reference incremented on each call.
The code would not decrement the dst refcount when the dst pointer was
identical from the previous iteration, causing the dst refcnt leak.
Testcase:
ip netns add TEST
ip netns exec TEST ip link set lo up
ip link add dummy0 type dummy
ip link add dummy1 type dummy
ip link add dummy2 type dummy
ip link set dev dummy0 netns TEST
ip link set dev dummy1 netns TEST
ip link set dev dummy2 netns TEST
ip netns exec TEST ip addr add 192.168.1.1/24 dev dummy0
ip netns exec TEST ip link set dummy0 up
ip netns exec TEST ip addr add 192.168.1.2/24 dev dummy1
ip netns exec TEST ip link set dummy1 up
ip netns exec TEST ip addr add 192.168.1.3/24 dev dummy2
ip netns exec TEST ip link set dummy2 up
ip netns exec TEST sctp_test -H 192.168.1.2 -P 20002 -h 192.168.1.1 -p 20000 -s -B 192.168.1.3

When going through the bind address list in sctp_v6_get_dst() and
the previously found address is better ('matchlen > bmatchlen'),
the code continues to the next iteration without releasing currently
held destination.
Fix it by releasing 'bdst' before continue to the next iteration, and
instead of introducing one more '!IS_ERR(bdst)' check for dst_release(),
move the already existed one right after ip6_dst_lookup_flow(), i.e. we
shouldn't proceed further if we get an error for the route lookup.

Merge tag 'xfs-4.16-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull more xfs updates from Darrick Wong:
"As promised, here's a (much smaller) second pull request for the
second week of the merge cycle. This time around we have a couple
patches shutting off unsupported fs configurations, and a couple of
cleanups.
Last, we turn off EXPERIMENTAL for the reverse mapping btree, since
the primary downstream user of that information (online fsck) is now
upstream and I haven't seen any major failures in a few kernel
releases.
Summary:
- Print scrub build status in the xfs build info.
- Explicitly call out the remaining two scenarios where we don't
support reflink and never have.
- Remove EXPERIMENTAL tag from reverse mapping btree!"
* tag 'xfs-4.16-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
xfs: remove experimental tag for reverse mapping

"This work from Amir adds NFS export capability to overlayfs. NFS
exporting an overlay filesystem is a challange because we want to keep

This is achieved by indexing copied up objects by lower layer file
handle. The index is already used for hard links, this patchset
extends the use to NFS file handle decoding"

Currently the async EQ has 256 entries only. It might not be big enough
for the SW to handle all the needed pending events. For example, in case
of many QPs (let's say 1024) connected to a SRQ created using NVMeOF target
and the target goes down, the FW will raise 1024 "last WQE reached" events
and may cause EQ overrun. Increase the EQ to more reasonable size, that beyond
it the FW should be able to delay the event and raise it later on using internal
backpressure mechanism.

The hip06 and hip08 run on a little endian ARM, it needs to
revise the annotations to indicate that the HW uses little
endian data in the various DMA buffers, and flow the necessary
swaps throughout.
The imm_data use big endian mode. The cpu_to_le32/le32_to_cpu
swaps are no-op for this, which makes the only substantive
change the handling of imm_data which is now mandatory swapped.

Stephane reported that we don't set properly PERIOD sample type for
events with period term defined.
Before:
$ perf record -e cpu/cpu-cycles,period=1000/u ls
$ perf evlist -v
cpu/cpu-cycles,period=1000/u: ... sample_type: IP|TID|TIME|PERIOD, ...
After:
$ perf record -e cpu/cpu-cycles,period=1000/u ls
$ perf evlist -v

Setting PERIOD sample type based on period term setup.
Committer note:
When we use -c or a period=N term in the event definition, then we don't
need to ask the kernel, for this event, via perf_event_attr.sample_type
|= PERF_SAMPLE_PERIOD, to put the event period in each sample for this
event, as we know it already, it is in perf_event_attr.sample_period.
