We can't reliably wait in io_ring_ctx_wait_and_kill(), since the
task_works list isn't ordered (in fact it's LIFO ordered). We could
either fix this with a separate task_works list for io_uring work, or
just punt the wait-and-free to async context. This ensures that
task_work that comes in while we're shutting down is processed
correctly. If we don't go async, we could have work past the fput()
work for the ring that depends on work that won't be executed until
after we're done with the wait-and-free. But as this operation is
blocking, it'll never get a chance to run.
This was reproduced with hundreds of thousands of sockets running
memcached, haven't been able to reproduce this synthetically.

Whenever we walk along the dma-fence-chain, we prune signaled links to
keep the chain nice and tidy. This leads to situations where we can
prune a link and report the earlier fence as the target seqno --
violating our own consistency checks that the seqno is not more advanced
than the last element in a dma-fence-chain.
Report a NULL fence and success if the seqno has already been signaled.

The problem is that because wait_pidfd.lock is taken under the tasklist
lock. It must always be taken with irqs disabled as tasklist_lock can be
taken from interrupt context and if wait_pidfd.lock was already taken this
would create a lock order inversion.
Oleg suggested just disabling irqs where I have added extra calls to
wait_pidfd.lock. That should be safe and I think the code will eventually
do that. It was rightly pointed out by Christian that sharing the
wait_pidfd.lock was a premature optimization.
It is also true that my pre-merge window testing was insufficient. So
remove the premature optimization and give struct pid a dedicated lock of
it's own for struct pid things. I have verified that lockdep sees all 3
paths where we take the new pid->lock and lockdep does not complain.
It is my current day dream that one day pid->lock can be used to guard the
task lists as well and then the tasklist_lock won't need to be held to
deliver signals. That will require taking pid->lock with irqs disabled.

Although it's not unexpected for drm_dp_check_act_status() to fail due
to DPCD read failures (as the hub may have just been unplugged
suddenly), timeouts are a bit more worrying as they either mean we need
a longer timeout value, or we aren't setting up payload allocations
properly. So, let's start printing errors on timeouts.

Currently we only poll for an ACT up to 30 times, with a busy-wait delay
of 100µs between each attempt - giving us a timeout of 2900µs. While
this might seem sensible, it would appear that in certain scenarios it
can take dramatically longer then that for us to receive an ACT. On one
of the EVGA MST hubs that I have available, I observed said hub
sometimes taking longer then a second before signalling the ACT. These
delays mostly seem to occur when previous sideband messages we've sent
are NAKd by the hub, however it wouldn't be particularly surprising if
it's possible to reproduce times like this simply by introducing branch
devices with large LCTs since payload allocations have to take effect on
every downstream device up to the payload's target.
So, instead of just retrying 30 times we poll for the ACT for up to 3ms,
and additionally use usleep_range() to avoid a very long and rude
busy-wait. Note that the previous retry count of 30 appears to have been
arbitrarily chosen, as I can't find any mention of a recommended timeout
or retry count for ACTs in the DisplayPort 2.0 specification. This also
goes for the range we were previously using for udelay(), although I
suspect that was just copied from the recommended delay for link
training on SST devices.
Changes since v1:
* Use readx_poll_timeout() instead of open-coding timeout loop - Sean
Paul
Changes since v2:
* Increase poll interval to 200us - Sean Paul
* Print status in hex when we timeout waiting for ACT - Sean Paul

Analogix_dp driver acquires all its resources in the ->bind() callback,
what is a bit against the component driver based approach, where the
driver initialization is split into a probe(), where all resources are
gathered, and a bind(), where all objects are created and a compound
driver is initialized.
Extract all the resource related operations to analogix_dp_probe() and
analogix_dp_remove(), then call them before/after registration of the
device components from the main Exynos DP and Rockchip DP drivers. Also
move the plat_data initialization to the probe() to make it available for
the analogix_dp_probe() function.
This fixes the multiple calls to the bind() of the DRM compound driver

"The main items are:
- support for asynchronous create and unlink (Jeff Layton).
Creates and unlinks are satisfied locally, without waiting for a
reply from the MDS, provided the client has been granted

Opt-in with the new nowsync mount option.
- multiple blk-mq queues for rbd (Hannes Reinecke and myself).
When the driver was converted to blk-mq, we settled on a single
blk-mq queue because of a global lock in libceph and some other
technical debt. These have since been addressed, so allocate a
queue per CPU to enhance parallelism.
- don't hold onto caps that aren't actually needed (Zheng Yan).

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm and dax updates from Dan Williams:
"There were multiple touches outside of drivers/nvdimm/ this round to
add cross arch compatibility to the devm_memremap_pages() interface,
enhance numa information for persistent memory ranges, and add a
zero_page_range() dax operation.
This cycle I switched from the patchwork api to Konstantin's b4 script
for collecting tags (from x86, PowerPC, filesystem, and device-mapper
folks), and everything looks to have gone ok there. This has all
appeared in -next with no reported issues.
Summary:
- Add support for region alignment configuration and enforcement to
fix compatibility across architectures and PowerPC page size
configurations.
- Introduce 'zero_page_range' as a dax operation. This facilitates
filesystem-dax operation without a block-device.
- Introduce phys_to_target_node() to facilitate drivers that want to
know resulting numa node if a given reserved address range was
onlined.
- Advertise a persistence-domain for of_pmem and papr_scm. The
persistence domain indicates where cpu-store cycles need to reach
in the platform-memory subsystem before the platform will consider
them power-fail protected.
- Promote numa_map_to_online_node() to a cross-kernel generic
facility.
- Save x86 numa information to allow for node-id lookups for reserved
memory ranges, deploy that capability for the e820-pmem driver.
- Pick up some miscellaneous minor fixes, that missed v5.6-final,
including a some smatch reports in the ioctl path and some unit
test compilation fixups.
- Fixup some flexible-array declarations"

For Arcturus, forcing clock to some specific level is not supported
with 54.18 and onwards SMU firmware. As according to firmware team,
they adopt new gfx dpm tuned parameters which can cover all the use
case in a much smooth way. Thus setting through driver interface
is not needed and maybe do a disservice.
