IO processing is done by the daemon when bio requests
are queued in dm-user. If there is no daemon, then
IO's will be hung indefinitely; This can lead
to sysrq kernel panic when llkd daemon detects
IO's hung in uninterruptible state.
Terminate the bio reqests as an IO error if there
is no daemon to process. We already track if
there are any user-space threads processing
IO's per dm-user targer. If there is no daemon,
queue the IO requests to a delayed work queue.
If the daemon does not show up within that time frame,
worker thread will fail the IO with an IO error.
Bug: 188362117
Test: 1: Kill the daemon when IO to dm-user is in-flight
Verify IO failure and no IO hang.
2: Verify daemon picks up IO's queued for cancelling.
3: Full and incremental OTA.
4: Terminate snapuserd daemon during post-install phase of OTA
5: Add user-space unit test to test (1)

When KBUILD_MIXED_TREE is set, vmlinux and related images come from an
out-of-tree location and vmlinux shouldn't be compiled. arch/arm64 and
arch/x86 add the default Images to all target, so remove that default
behavior when KBUILD_MIXED_TREE is set.
This when an out-of-tree module, e.g. virtual-device, runs "make all"
instead of "make modules".

- Extend subdirectory expressions to also include recursively
- Combine expressions with common owners
- Minor cleanups
Note, the way expressions are evaluated in the code-owners plugin (as
of now and for compatibility with the `find-owners` plugin), means we
match slightly more than expected, even with just the single asterisk.
As expressions like `net*` are implicitly treated like `{**/,}net*`,
we would not only match net_something.h and net_filter/header.h, but
also (unexpectedly) platform/net_something.h.
This change does not make things better in this regards, but for all the
above mentioned points, this is an improvement.

The initialization of MIDI devices that are found on some LINE6
drivers are currently done in a racy way; namely, the MIDI buffer
instance is allocated and initialized in each private_init callback
while the communication with the interface is already started via
line6_init_cap_control() call before that point. This may lead to
Oops in line6_data_received() when a spurious event is received, as
reported by syzkaller.
This patch moves the MIDI initialization to line6_init_cap_control()
as well instead of the too-lately-called private_init for avoiding the
race. Also this reduces slightly more lines, so it's a win-win
change.

Commit 871f1f2bcb ("platform/x86: intel_int0002_vgpio: Only implement
irq_set_wake on Bay Trail") stopped passing irq_set_wake requests on to
the parents IRQ because this was breaking suspend (causing immediate
wakeups) on an Asus E202SA.
This workaround for the Asus E202SA is causing wakeup by USB keyboard to
not work on other devices with Airmont CPU cores such as the Medion Akoya
E1239T. In hindsight the problem with the Asus E202SA has nothing to do
with Silvermont vs Airmont CPU cores, so the differentiation between the
2 types of CPU cores introduced by the previous fix is wrong.
The real issue at hand is s2idle vs S3 suspend where the suspend is
mostly handled by firmware. The parent IRQ for the INT0002 device is shared
with the ACPI SCI and the real problem is that the INT0002 code should not
be messing with the wakeup settings of that IRQ when suspend/resume is
being handled by the firmware.
Note that on systems which support both s2idle and S3 suspend, which
suspend method to use can be changed at runtime.
This patch fixes both the Asus E202SA spurious wakeups issue as well as
the wakeup by USB keyboard not working on the Medion Akoya E1239T issue.
These are both fixed by replacing the old workaround with delaying the
enable_irq_wake(parent_irq) call till system-suspend time and protecting
it with a !pm_suspend_via_firmware() check so that we still do not call
it on devices using firmware-based (S3) suspend such as the Asus E202SA.
Note rather then adding #ifdef CONFIG_PM_SLEEP, this commit simply adds
a "depends on PM_SLEEP" to the Kconfig since this drivers whole purpose
is to deal with wakeup events, so using it without CONFIG_PM_SLEEP makes
no sense.

The poll function should not return -ERESTARTSYS.
Furthermore, locking in this function is completely unnecessary. The
ddev->lock protects access to the main device and controller (ddev->dev
and ddev->ctrl), ensuring that both are and remain valid while being
accessed by clients. Both are, however, never accessed in the poll
function. The shutdown test (via atomic bit flags) be safely done
without locking, so drop locking here entirely.

Although many DICE-based devices have a quirk at high sampling transfer
frequency to multiplex double number of PCM frames into data block than
the number in IEC 61883-1/6, the above devices are just compliant to
IEC 61883-1/6.
This commit disables the mode of double_pcm_frames for the models.
