selftests/tracing: Fix test_multiple_writes stall
When /sys/kernel/tracing/buffer_size_kb is less than 12KB,
the test_multiple_writes test will stall and wait for more
input due to insufficient buffer space.
Check current buffer_size_kb value before the test. If it is
less than 12KB, it temporarily increase the buffer to 12KB,
and restore the original value after the tests are completed.

We have to resort to a bit of a hack: python-libevdev gets the
properties from libevdev at module init time. If libevdev hasn't been
rebuilt with the new property it won't be automatically populated. So we
hack around this by constructing the property manually.

Instead of multiple spellings of a string-provided argument, let's make

And while we do this fix the two wrong devices:
- elan_04f3_313a (HP ZBook Fury 15) is discrete button pad
- dell_044e_1220 (Dell Precision 7740) is a discrete button pad

This commit adds a test case for netdevsim carrier state consistency.
Specifically, the added test verifies the carrier state during the
following operations:
1. Unlink two netdevsims
2. ifdown one netdevsim, then ifup again
3. Link the netdevsims again
4. ifdown one netdevsim, then ifup again
These steps verifies that the carrier is UP iff two netdevsims are
linked and ifuped.

xerror() terminates execution by calling exit(), but it is not visible

When building kselftests with a toolchain that enables source
fortification (e.g., Android's build environment, which uses
-D_FORTIFY_SOURCE=3), a build failure occurs in tests that use an
empty FIXTURE().
The root cause is that an empty fixture struct results in
`sizeof(self_private)` evaluating to 0. The compiler's fortification
checks then detect the `memset()` call with a compile-time constant size
of 0, issuing a `-Wuser-defined-warnings` which is promoted to an error
by `-Werror`.
An initial attempt to guard the call with `if (sizeof(self_private) > 0)`
was insufficient. The compiler's static analysis is aggressive enough
to flag the `memset(..., 0)` pattern before evaluating the conditional,
thus still triggering the error.
To resolve this robustly, this change introduces a `static inline`
helper function, `__kselftest_memset_safe()`. This function wraps the
size check and the `memset()` call. By replacing the direct `memset()`
in the `__TEST_F_IMPL` macro with a call to this helper, we create an
abstraction boundary. This prevents the compiler's static analyzer from
"seeing" the problematic pattern at the macro expansion site, resolving
the build failure.

'available_events' is actually not required by
'test.d/event/toplevel-enable.tc' and its Existence has been tested in
'test.d/00basic/basic4.tc'.
So the require of 'available_events' can be dropped and then we can add
'instance' flag to test 'test.d/event/toplevel-enable.tc' for instance.

Add test_generic_15.sh to verify that async partition scan prevents
IO hang when reading partition tables.
The test creates ublk devices with fault_inject target and very large
delay (60s) to simulate blocked partition table reads, then kills the
daemon to verify proper state transitions without hanging:
1. Without recovery support:
- Create device with fault_inject and 60s delay
- Kill daemon while partition scan may be blocked
- Verify device transitions to DEAD state
2. With recovery support (-r 1):
- Create device with fault_inject, 60s delay, and recovery
- Kill daemon while partition scan may be blocked
- Verify device transitions to QUIESCED state
Before the async partition scan fix, killing the daemon during
partition scan would cause deadlock as partition scan held ub->mutex
while waiting for IO. With the async fix, partition scan happens in
a work function and flush_work() ensures proper synchronization.
Add _add_ublk_dev_no_settle() helper function to skip udevadm settle,
which would otherwise hang waiting for partition scan events to
complete when partition table read is delayed.

The recent introduction of the libopenssl feature test forgot to add the

Noticed by looking at this file after building:

It was added only to the individual ssl test, that works:

oot build tends to help uncover bugs so it's worth keeping around,
as long as it's low effort.
add stubs for a couple of macros virtio gained recently,
and disable vdpa in the test build.
