Currently, torture.sh assumes excessive levels of reviewer competence
and thus fails to gracefully handle cases where it is tricked into giving
kvm.sh invalid arguments. This commit therefore upgrades error handling
to more gracefully handle this situation.

This commit causes the torture.sh --do-allmodconfig and --do-rcu-rust
parameters to add testid.txt files to their results directories, thus
allowing easier analysis of the results of a series of runs kicked off by
"git bisect".

The kvm.sh script places a testid.txt file in the top-level results
directory in order to identify the tree and commit that was tested.
This works well, but there are scripts other than kvm.sh that also create
results directories, and it would be good for them to also identify
exactly what was tested.
This commit therefore extracts the testid.txt generation to a new
mktestid.sh script so that it can be easily used elsewhere.

When torture.sh is told to do nothing, it produces a couple of distracting
diagnostics from the "find" command:
find: ‘’: No such file or directory
find: ‘’: No such file or directory
This is pointless chatter and could cause confusion. This commit therefore
suppresses these diagnostics when there is nothing to find.

The arm64 architecture requires that KCSAN-enabled kernels be built with
the CONFIG_EXPERT=y Kconfig option. This commit therefore causes the
torture.sh script to provide this option, but only for --kcsan runs on
arm64 systems.

Describing the dependencies between registers and features is on
the masochistic side of things, with hard-coded values that would
be better taken from the existing description.
Add a couple of helpers to that effect, and repaint the dependency

With the latest llvm21 compiler, I hit several errors when building bpf
selftests. Some of errors look like below:
test_maps.c:565:40: error: variable 'val' is uninitialized when passed as a
const pointer argument here [-Werror,-Wuninitialized-const-pointer]
565 | assert(bpf_map_update_elem(fd, NULL, &val, 0) < 0 &&
| ^~~
prog_tests/bpf_iter.c:400:25: error: variable 'c' is uninitialized when passed
as a const pointer argument here [-Werror,-Wuninitialized-const-pointer]
400 | write(finish_pipe[1], &c, 1);
| ^
Some other errors have similar the pattern as the above.
These errors are fixed by initializing those variables properly.

From Dave [1]:
"""
It was a mistake to introduce core/acpi.c and putting ACPI dependency on
cxl_core when adding the extended linear cache support.
"""
Current implementation calls hmat_get_extended_linear_cache_size() of
the ACPI subsystem. That external reference causes issue running
cxl_test as there is no way to "mock" that function and ignore it when
using cxl test.
Instead of working around that using cxlrd ops and extensively
expanding cxl_test code [1], just move HMAT calls out of the core
module to cxl_acpi. Implement this by adding a @cache_size member to
struct cxl_root_decoder. During initialization the cache size is
determined and added to the root decoder object in cxl_acpi. Later on
in cxl_core the cache_size parameter is used to setup extended linear
caching.

'struct thread' is task local structure, and the related code will become
more readable if we pass it via parameter.
Meantime pass 'ublk_thread *' to ublk_io_alloc_sqes(), and this way is
natural since we use per-thread io_uring for handling IO.
More importantly it helps much for removing the current ubq_daemon or

parents
As described in a previous commit [1], Lion's patch [2] revealed an ancient
bug in the qdisc API. Whenever a user tries to add a qdisc to an
invalid parent (not a class, root, or ingress qdisc), the qdisc API will
detect this after qdisc_create is called. Some qdiscs (like fq_codel, pie,
and sfq) call functions (on their init callback) which assume the parent is
valid, so qdisc_create itself may have caused a NULL pointer dereference in
such cases.
This commit creates 3 TDC tests that attempt to add fq_codel, pie and sfq
qdiscs to invalid parents
- Attempts to add an fq_codel qdisc to an hhf qdisc parent
- Attempts to add a pie qdisc to a drr qdisc parent
- Attempts to add an sfq qdisc to an inexistent hfsc classid (which would
belong to a valid hfsc qdisc)

Patch series "selftests/damon: add python and drgn based DAMON sysfs
functionality tests".
DAMON sysfs interface is the bridge between the user space and the kernel
space for DAMON parameters. There is no good and simple test to see if
the parameters are set as expected. Existing DAMON selftests therefore
test end-to-end features. For example, damos_quota_goal.py runs a DAMOS
scheme with quota goal set against a test program running an artificial
access pattern, and see if the result is as expected. Such tests cover
only a few part of DAMON. Adding more tests is also complicated.
Finally, the reliability of the test itself on different systems is bad.
'drgn' is a tool that can extract kernel internal data structures like
DAMON parameters. Add a test that passes specific DAMON parameters via
DAMON sysfs reusing _damon_sysfs.py, extract resulting DAMON parameters
via 'drgn', and compare those. Note that this test is not adding
exhaustive tests of all DAMON parameters and input combinations but very
basic things. Advancing the test infrastructure and adding more tests are
future works.
This patch (of 6):
'drgn' is a useful tool for extracting kernel internal data structures
such as DAMON's parameter and running status. Add a 'drgn' script that
extracts such DAMON internal data at runtime, for using it as a tool for
seeing if a test input has made expected results in the kernel.
The script saves or prints out the DAMON internal data as a json file or
string. This is for making use of it not very depends on 'drgn'. If
'drgn' is not available on a test setup and we find alternative tools for
doing that, the json-based tests can be updated to use an alternative tool
in future.
Note that the script is tested with 'drgn v0.0.22'.

The test_kmem_dead_cgroups test currently assumes that RCU and
memory reclaim will complete within 5 seconds. In some environments
this timeout may be insufficient, leading to spurious test failures.
This patch introduces max_time set to 20 which is then used in the
test. After 5th sec the debug message is printed to indicate the
cleanup is still ongoing.
In the system under test with 16 CPUs the original test was failing
most of the time and the cleanup time took usually approx. 6sec.
Further tests were conducted with and without do_rcu_barrier and the
results (respectively) are as follow:

The iou-zcrx selftest currently runs the server on the remote host
and the client on the local host. This commit flips the endpoints
such that server runs on localhost and client on remote.
This change brings the iou-zcrx selftest in convention with other
selftests.
Drive-by fix for a missing import exception that happens when the
network interface has less than 2 combined channels.
Test plan: ran iou-zcrx.py selftest between 2 physical machines
