Currently running tests via KUnit tool means tweaking a .kunitconfig
file, which you'd keep around locally and never commit.
This changes makes it so users can pass in a path to a kunitconfig.
One of the imagined use cases is having kunitconfig fragments in-tree
to formalize interesting sets of tests for features/subsystems, e.g.
$ ./tools/testing/kunit/kunit.py run --kunticonfig=fs/ext4/kunitconfig
For now, this hypothetical fs/ext4/kunitconfig would contain
CONFIG_KUNIT=y
CONFIG_EXT4_FS=y
CONFIG_EXT4_KUNIT_TESTS=y
At the moment, it's not hard to manually whip up this file, but as more
and more tests get added, this will get tedious.
It also opens the door to documenting how to run all the tests relevant
to a specific subsystem or feature as a simple one-liner.
This can be seen as an analogue to tools/testing/selftests/*/config
But in the case of KUnit, the tests live in the same directory as the
code-under-test, so it feels more natural to allow the kunitconfig
fragments to live anywhere. (Though, people could create a separate
directory if wanted; this patch imposes no restrictions on the path).

Don't use an O(nm) algorithm* and make it more readable by using a dict.

Also take this time to rename get_absolute_path() to test_data_path().
1. the name is currently a lie. It gives relative paths, e.g. if I run
from the same dir as the test file, it gives './test_data/<file>'
See https://docs.python.org/3/reference/import.html#__file__, which
doesn't stipulate that implementations provide absolute paths.
2. it's only used for generating paths to tools/testing/kunit/test_data/
So we can tersen things by making it less general.
Cache the absolute path to the test data files per suggestion from [1].
Using relative paths, the tests break because of this code in kunit.py
if get_kernel_root_path():
os.chdir(get_kernel_root_path())

The use of manual open() and .close() calls seems to be an attempt to
keep the contents in scope.
But Python doesn't restrict variables like that, so we can introduce new
variables inside of a `with` and use them outside.

Pull libnvdimm fixes from Dan Williams:
"A fix for a crash scenario that has been present since the initial
merge, a minor regression in sysfs attribute visibility, and a fix for
some flexible array warnings.
The bulk of this pull is an update to the libnvdimm unit test
infrastructure to test non-ACPI platforms. Given there is zero
regression risk for test updates, and the tests enable validation of
bits headed towards the next merge window, I saw no reason to hold the
new tests back. Santosh originally submitted this before the v5.11

Summary:
- Fix a crash when sysfs accesses race 'dimm' driver probe/remove.

Therefore, define two new constants to be used by SUD's selector variable

In a real dma mapping user case, after dma_map is done, data will be
transmit. Thus, in multi-threaded user scenario, IOMMU contention
should not be that severe. For example, if users enable multiple
threads to send network packets through 1G/10G/100Gbps NIC, usually
the steps will be: map -> transmission -> unmap. Transmission delay
reduces the contention of IOMMU.
Here a delay is added to simulate the transmission between map and unmap
so that the tested result could be more accurate for TX and simple RX.
A typical TX transmission for NIC would be like: map -> TX -> unmap
since the socket buffers come from OS. Simple RX model eg. disk driver,
is also map -> RX -> unmap, but real RX model in a NIC could be more
complicated considering packets can come spontaneously and many drivers
are using pre-mapped buffers pool. This is in the TBD list.

Add a memslot modification stress test in which a memslot is repeatedly
created and removed while vCPUs access memory in another memslot. Most
userspaces do not create or remove memslots on running VMs which makes
it hard to test races in adding and removing memslots without a
dedicated test. Adding and removing a memslot also has the effect of
tearing down the entire paging structure, which leads to more page
faults and pressure on the page fault handling path than a one-and-done
memory population test.

This is because it assumes that tmp_dir_path can be a maximum of 64

not using a fixed size in the initialization of tmp_dir_path which

When BPF_FETCH is set, atomic instructions load a value from memory
into a register. The current verifier code first checks via
check_mem_access whether we can access the memory, and then checks
via check_reg_arg whether we can write into the register.
For loads, check_reg_arg has the side-effect of marking the
register's value as unkonwn, and check_mem_access has the side effect
of propagating bounds from memory to the register. This currently only
takes effect for stack memory.
Therefore with the current order, bounds information is thrown away,
but by simply reversing the order of check_reg_arg
vs. check_mem_access, we can instead propagate bounds smartly.
A simple test is added with an infinite loop that can only be proved
unreachable if this propagation is present. This is implemented both
with C and directly in test_verifier using assembly.

We want to use stdout to return lists of devices, etc so log debug / status
messages to stderr rather than stdout.

Hoist some of the useful test environment checking and prep code into
eeh-functions.sh so they can be reused in other tests.

This is the NCI test suite. It tests the NFC/NCI module using virtual NCI
device. Test cases consist of making the virtual NCI device on/off and
controlling the device's polling for NCI1.0 and NCI2.0 version.

Those hooks run as BPF_CGROUP_RUN_SA_PROG_LOCK and operate on a locked socket.
Note that we could remove the switch for prog->expected_attach_type altogether
since all current sock_addr attach types are covered. However, it makes sense
to keep it as a safe-guard in case new sock_addr attach types are added that
might not operate on a locked socket. Therefore, avoid to let this slip through.
