"The new features of this release:
- Added TRACE_DEFINE_SIZEOF() which allows trace events that use

that trace-cmd and perf can parse them correctly.
- Some rework of the TRACE_DEFINE_ENUM() such that the above
TRACE_DEFINE_SIZEOF() could reuse the same code.
- Recording of tgid (Thread Group ID). This is similar to how task
COMMs are recorded (cached at sched_switch), where it is in a table

- Have ":mod:<module>" be cached when written into set_ftrace_filter.
Then the functions of the module will be traced at module load.

"This includes two bugs against the newly added opa vnic that were
found by turning on the debug kernel options:
- sleeping while holding a lock, so a one line fix where they
switched it from GFP_KERNEL allocation to a GFP_ATOMIC allocation
- a case where they had an isolated caller of their code that could
call them in an atomic context so they had to switch their use of a
mutex to a spinlock to be safe, so this was considerably more lines
of diff because all uses of that lock had to be switched
In addition, the bug that was discussed with you already about an out
of bounds array access in ib_uverbs_modify_qp and ib_uverbs_create_ah
and is only seven lines of diff.
And finally, one fix to an earlier fix in the -rc cycle that broke
hfi1 and qib in regards to IPoIB (this one is, unfortunately, larger
than I would like for a -rc7 submission, but fixing the problem
required that we not treat all devices as though they had allocated a
netdev universally because it isn't true, and it took 70 lines of diff
to resolve the issue, but the final patch has been vetted by Intel and
Mellanox and they've both given their approval to the fix).

- Two fixes for OPA found by debug kernel
- Fix for user supplied input causing kernel problems
- Fix for the IPoIB fixes submitted around -rc4"

- Allwinner Sunxi A83T R_PIO.
- Marvell MVEBU Armada CP110 and AP806.
- Intel Cannon Lake PCH.
- Qualcomm IPQ8074.

- STM32 has improved GPIO support.
- Samsung Exynos drivers are split per ARMv7 and ARMv8.
- Marvell MVEBU is converted to use regmap for register access.

- SEAD3 is using the generic leds-syscon & regmap based

reorganization / optimization thereafter
- Improved support of PCM ack ops, and a new ABI for improved
control/status mmap handling
- Lots of constifications in various codes

Pull mnt namespace updates from Eric Biederman:
"A big break-through came during this development cycle as a way was
found to maintain the existing umount -l semantics while allowing for
optimizations that improve the performance. That is represented by the
first change in this series moving the reparenting of mounts into
their own pass. This has allowed addressing the horrific performance
of umount -l on a carefully crafted tree of mounts with locks held
(0.06s vs 60s in my testing). What allowed this was not changing where
umounts propagate to while propgating umounts.
The next change fixes the case where the order of the mount whose
umount are being progated visits a tree where the mounts are stacked
upon each other in another order. This is weird but not hard to
implement.
The final change takes advantage of the unchanging mount propgation
tree to skip parts of the mount propgation tree that have already been
visited. Yielding a very nice speed up in the worst case.
There remains one outstanding question about the semantics of umount -l
that I am still discussiong with Ram Pai. In practice that area of the
semantics was changed by
1064f874abc0 ("mnt: Tuck mounts under others
instead of creating shadow/side mounts.") and no regressions have been
reported. Still I intend to finish talking that out with him to ensure
there is not something a more intense use of mount propagation in the

"We've got eight GFS2 patches for this merge window:
- Andreas Gruenbacher has four patches related to cleaning up the

shrinker: Shrinker calls gfs2 evict, evict calls DLM, DLM requires
memory and blocks on the shrinker.
These four patches have been well tested. His second set of patches
are still being tested, so I plan to hold them until the next merge
window, after we have more weeks of testing. The first patch
eliminates the flush_delayed_work, which can block.
- Andreas's second patch protects setting of gl_object for rgrps with
a spin_lock to prevent proven races.
- His third patch introduces a centralized mechanism for queueing
glock work with better reference counting, to prevent more races.
-His fourth patch retains a reference to inode glocks when an error
occurs while creating an inode. This keeps the subsequent evict
from needing to reacquire the glock, which might call into DLM and
block in low memory conditions.
- Arvind Yadav has a patch to add const to attribute_group
structures.
- I have a patch to detect directory entry inconsistencies and
withdraw the file system if any are found. Better that than silent
corruption.

dm zoned: fix overflow when converting zone ID to sectors
A zone ID is a 32 bits unsigned int which can overflow when doing the
bit shifts in dmz_start_sect(). With a 256 MB zone size drive, the
overflow happens for a zone ID >= 8192.
Fix this by casting the zone ID to a sector_t before doing the bit
shift. While at it, similarly fix dmz_start_block().

Cavium CNN55XX: fix broken default Kconfig entry
Every developer always thinks that _their_ code is so special and
magical that it should be enabled by default.
And most of them are completely and utterly wrong. That's definitely
the case when you write a specialty driver for a very unsual "security
processor". It does *not* get to mark itself as "default m".

gfs2_evict_inode instead to get rid of the flushing.
In addition, flush the work queues of existing glocks before reusing
them for new inodes to get those glocks into a known state: the glock

nfp: default to chained metadata prepend format
ABI 4.x introduced the chained metadata format and made it the
only one possible. There are cases, however, where the old
format is preferred - mostly to make interoperation with VFs
using ABI 3.x easier for the datapath. In ABI 5.x we allowed
for more flexibility by selecting the metadata format based
on capabilities. The default was left to non-chained.
In case of fallback traffic, there is no capability telling the
driver there may be chained metadata. With a very stripped-
-down FW the default old metadata format would be selected
making the driver drop all fallback traffic.
This patch changes the default selection in the driver. It
should not hurt with old firmwares, because if they don't
advertise RSS they will not produce metadata anyway. New
firmwares advertising ABI 5.x, however, can depend on the
driver defaulting to chained format.

nfp: improve order of interfaces in breakout mode
For historical reasons we enumerate the vNICs in order. This means
that if user configures breakout on a multiport card, the first
interface of the second port will have its MAC address changed.
What's worse, when moved from static information (HWInfo) to using
management FW (NSP), more features started depending on the port ids.
Right now in case of breakout first subport of the second port and
second subport of the first port will have their link info swapped.
Revise the ordering scheme so that first subport maintains its address.
Side effect of this change is that we will use base lane ids in
devlink (i.e. 40G ports will be 4 ids apart), e.g.:
pci/0000:04:00.0/0: type eth netdev p6p1
pci/0000:04:00.0/4: type eth netdev p6p2
Note that behaviour of phys_port_id is not changed since there is
a separate id number for the subport there.

Merge branch 'net-subsystem-misc-refcounter-conversions'
Elena Reshetova says:
====================
v2 net subsystem misc refcounter conversions
Changes in v2:
* rebase on top of net-next
* currently by default refcount_t = atomic_t (*) and uses all
atomic standard operations unless CONFIG_REFCOUNT_FULL is enabled.
This is a compromise for the systems that are critical on
performance (such as net) and cannot accept even slight delay
on the refcounter operations.
This series, for various misc network components, replaces atomic_t reference
counters with the new refcount_t type and API (see include/linux/refcount.h).
By doing this we prevent intentional or accidental
underflows or overflows that can led to use-after-free vulnerabilities.
These are the last networking-related conversions with the exception of
network drivers (to be send separately).
Please excuse the long patch set, but seems like breaking it up
won't save that much on CC list and most of the changes are
trivial.
The patches are fully independent and can be cherry-picked separately.
In order to try with refcount functionality enabled in run-time,
CONFIG_REFCOUNT_FULL must be enabled.
NOTE: automatic kernel builder for some reason doesn't like all my
network branches and regularly times out the builds on these branches.
Suggestion for "waiting a day for a good coverage" doesn't work, as
we have seen with generic network conversions. So please wait for the
full report from kernel test rebot before merging further up.
This has been compile-tested in 116 configs, but 71 timed out (including
all s390-related configs again). I am trying to see if they can fix
build coverage for me in meanwhile.
