92318f20d7 f2fs: preserve direct write semantics when buffering is forced
In some cases, e.g. for zoned block devices, direct writes are
forced into buffered writes that will populate the page cache
and be written out just like buffered io.

Direct reads, on the other hand, is supported for the zoned
block device case. This has the effect that applications
built for direct io will fill up the page cache with data
that will never be read, and that is a waste of resources.

If we agree that this is a problem, how do we fix it?

A) Supporting proper direct writes for zoned block devices would
be the best, but it is currently not supported (probably for
a good but non-obvious reason). Would it be feasible to
implement proper direct IO?

B) Avoid the cost of keeping unwanted data by syncing and throwing
out the cached pages for buffered O_DIRECT writes before completion.

This patch implements B) by reusing the code for how partial
block writes are flushed out on the "normal" direct write path.

Note that this changes the performance characteristics of f2fs
quite a bit.

Direct IO performance for zoned block devices is lower for
small writes after this patch, but this should be expected
with direct IO and in line with how f2fs behaves on top of
conventional block devices.

Another open question is if the flushing should be done for
all cases where buffered writes are forced.

      - set_page_writeback() [2st writeback]

This problem was introduced by the previous commit 7377e85396 ("f2fs:
compress: fix potential deadlock of compress file"). All pagelocks were
released in f2fs_write_raw_pages(), but whether the page was
in the writeback state was ignored in the subsequent writing process.
Let's fix it by waiting for the page to writeback before writing.

6797ebc4ac f2fs: Fix discard bug on zoned block devices with 2MiB zone size
When using f2fs on a zoned block device with 2MiB zone size, IO errors
occurs because f2fs tries to write data to a zone that has not been reset.

The cause is that f2fs tries to discard multiple zones at once. This is
caused by a condition in f2fs_clear_prefree_segments that does not check
for zoned block devices when setting the discard range. This leads to
invalid reset commands and write pointer mismatches.

This patch fixes the zoned block device with 2MiB zone size to reset one
zone at a time.

8f8cf76758 s390/vfio-ap: fix memory leak in vfio_ap device driver
The device release callback function invoked to release the matrix device
uses the dev_get_drvdata(device *dev) function to retrieve the
pointer to the vfio_matrix_dev object in order to free its storage. The
problem is, this object is not stored as drvdata with the device; since the
kfree function will accept a NULL pointer, the memory for the
vfio_matrix_dev object is never freed.

Since the device being released is contained within the vfio_matrix_dev
object, the container_of macro will be used to retrieve its pointer.

 "We discovered a filesystem summary counter corruption problem that was

  dying cpus and hence misses those counter values if the cpu shutdown
  hooks have not yet run to merge the values.

  I'm hoping this is a fairly painless fix to the problem, since the
  dying cpu mask should generally be empty. It's been in for-next for a
  week without any complaints from the bots.

   - Fix a race in the percpu counters summation code where the

 "This batch started with some debugging enhancements to the new

  As for more serious code changes -- there's a bug fix to make the
  lockless allocator scan the whole filesystem before resorting to the
  locking allocator. We're also adding a selftest for the venerable
  directory/xattr hash function to make sure that it produces consistent
  results so that we can address any fallout as soon as possible.

   - Add a few debugging assertions so that people (me) trying to port
     code to the new allocator functions don't mess up the caller
     requirements

   - Relax some overly cautious lock ordering enforcement in the new
     allocator code, which means that file allocations will locklessly
     scan for the best space they can get before backing off to the
     traditional lock-and-really-get-it behavior

Pull ARM SoC fixes from Arnd Bergmann:
 "As usual, most of the bug fixes address issues in the devicetree
  files, and out of these, most are for the Qualcomm and NXP platforms,
  including:

   - A missing 'reserved-memory' property on LG G Watch R that is needed
     to prevent clashing with firmware

   - Annotations for cache coherency on multiple machines

   - Corrections for pinctrl, regulator, clock, iommu and power domain
     properties for i.MX and Qualcomm to correctly reflect the hardware
     settings

   - Firmware file names on multiple machines SA8540P Ride board

   - An incompatible change to the qcom vadc driver requires adding
     individual labels

   - Fix EQoS PHY reset GPIO by dropping the deprecated/wrong property
     and switch to the new bindings.

   - A fix for PCI bus address translation Tegra194 and Tegra234.

  There are also a couple of device driver fixes, addressing:

   - A race condition in the amdtee driver

   - A performance regression in the Qualcomm 'llcc' driver

   - An unitialized variable use NXP i.MX 'weim' driver

   - Error handling issues in Qualcomm 'rmtfs', and 'scm' drivers and
     the Arm scmi firmware driver"
