Pull xfs bug fixes from Dave Chinner:
 "Largely minor bug fixes and cleanups, th emost important of which are
  probably the fixes for regressions in the extent allocation code:

   - fixes for inode garbage collection shutdown racing with work queue
     updates

   - ensure inodegc workers run on the CPU they are supposed to

   - disable counter scrubbing until we can exclusively freeze the
     filesystem from the kernel

   - regression fixes for new allocation related bugs

  xfs: fix xfs_inodegc_stop racing with mod_delayed_work
  xfs: disable reaping in fscounters scrub
  xfs: check that per-cpu inodegc workers actually run on that cpu
  xfs: explicitly specify cpu when forcing inodegc delayed work to run immediately
  xfs: fix negative array access in xfs_getbmap

c75f5a5506 fbdev: imsttfb: Fix use after free bug in imsttfb_probe
A use-after-free bug may occur if init_imstt invokes framebuffer_release
and free the info ptr. The caller, imsttfb_probe didn't notice that and
still keep the ptr as private data in pdev.

If we remove the driver which will call imsttfb_remove to make cleanup,
UAF happens.

Fix it by return error code if bad case happens in init_imstt.

105131df9c Devicetree binding fixes for v6.4
Few fixes for Devicetree bindings and related docs, all for issues
 introduced in v6.4-rc1 commits:
 
 1. media/ov2685: fix number of possible data lanes, as old binding
    explicitly mentioned one data lane. This fixes dt_binding_check
    warnings like:
    Documentation/devicetree/bindings/media/rockchip-isp1.example.dtb: camera@3c: port:endpoint:data-lanes: [[1]] is too short
    From schema: Documentation/devicetree/bindings/media/i2c/ovti,ov2685.yaml
 
 2. Maintainers: correct path of Apple PWM binding. This fixes
    refcheckdocs warning.
 
 3. PCI/fsl,imx6q: correct parsing of assigned-clocks and related
    properties and make the clocks more specific per PCI device (host or
    endpoint).  This fixes dtschema limitation and dt_binding_check
    warnings like:
 
    Documentation/devicetree/bindings/pci/fsl,imx6q-pcie-ep.example.dtb: pcie-ep@33800000: Unevaluated properties are not allowed
    From schema: Documentation/devicetree/bindings/pci/fsl,imx6q-pcie-ep.yaml

Smatch complains that:
arcfb_probe() warn: 'irq' from request_irq() not released on lines: 587.

Fix error handling in the arcfb_probe() function. If IO addresses are
not provided or framebuffer registration fails, the code will jump to
the err_addr or err_register_fb label to release resources.
If IRQ request fails, previously allocated resources will be freed.

79c901c935 drm/i915: taint kernel when force probing unsupported devices
For development and testing purposes, the i915.force_probe module
parameter and DRM_I915_FORCE_PROBE kconfig option allow probing of
devices that aren't supported by the driver.

The i915.force_probe module parameter is "unsafe" and setting it taints
the kernel. However, using the kconfig option does not.

Always taint the kernel when force probing a device that is not
supported.

v2: Drop "depends on EXPERT" to avoid build breakage (kernel test robot)

drm_dp_dsc_sink_max_slice_count() may return 0 if something goes
wrong on the part of the DSC sink and its DPCD register. This null
value may be later used as a divisor in intel_dsc_compute_params(),
which will lead to an error.
In the unlikely event that this issue occurs, fix it by testing the
return value of drm_dp_dsc_sink_max_slice_count() against zero.

intel_atomic_get_new_crtc_state can return NULL, unless crtc state wasn't
obtained previously with intel_atomic_get_crtc_state, so we must check it
for NULLness here, just as in many other places, where we can't guarantee
that intel_atomic_get_crtc_state was called.
We are currently getting NULL ptr deref because of that, so this fix was

[Description]
- Due to bandwidth / arbitration issues at 200Mhz DCFCLK,
  we want to enforce minimum 60us of prefetch to avoid
  intermittent underflow issues
- Since 60us prefetch is already enforced for UCLK DPM0,
  and many DCFCLK's > 200Mhz are mapped to UCLK DPM1, in
  theory there should not be any UCLK DPM regressions by
  enforcing greater prefetch

====================
af_unix: Fix two data races reported by KCSAN.

KCSAN reported data races around these two fields for AF_UNIX sockets.

  * sk->sk_receive_queue->qlen
  * sk->sk_shutdown

Let's annotate them properly.

e1d09c2c2f af_unix: Fix data races around sk->sk_shutdown.
KCSAN found a data race around sk->sk_shutdown where unix_release_sock()
and unix_shutdown() update it under unix_state_lock(), OTOH unix_poll()
and unix_dgram_poll() read it locklessly.

We need to annotate the writes and reads with WRITE_ONCE() and READ_ONCE().

679ed006d4 af_unix: Fix a data race of sk->sk_receive_queue->qlen.
KCSAN found a data race of sk->sk_receive_queue->qlen where recvmsg()
updates qlen under the queue lock and sendmsg() checks qlen under
unix_state_sock(), not the queue lock, so the reader side needs
READ_ONCE().

80e62bc848 MAINTAINERS: re-sort all entries and fields
It's been a few years since we've sorted this thing, and the end result
is that we've added MAINTAINERS entries in the wrong order, and a number
of entries have their fields in non-canonical order too.

So roll this boulder up the hill one more time by re-running

   ./scripts/parse-maintainers.pl --order

on it.

This file ends up being fairly painful for merge conflicts even
normally, since unlike almost all other kernel files it's one of those
"everybody touches the same thing", and re-ordering all entries is only
going to make that worse.  But the alternative is to never do it at all,
and just let it all rot..

The rc2 week is likely the quietest and least painful time to do this.

f7dcc5e33c firewire: net: fix unexpected release of object for asynchronous request packet
