Use parameterized test IDs for this waiver.
test_attention_backend is parameterized with ids=lambda n: n, so collected items use IDs such as unittest/_torch/attention/test_attention_backends.py::test_attention_backend[<name>]. apply_waives compares each collected item.nodeid to the waiver key exactly. The bare selector does not match those parameterized IDs, so the affected cases remain unwaived. Replace it with the supported parameterized selectors for the intended cases.

Sort the waiver entries to pass pre-commit.
The supplied pipeline log reports that file-contents-sorter rewrites this file. Run the hook and commit its sorted output so the Release Checks pre-commit job passes.

Pull request was closed
There are many test cases failed intermittently with relatively high failure rate, bigger than 20%. To reduce the impact to devs, waive them first.
There is a PR #20471 to fix that problem in review.
Waive the attention unit-test functions that fail once a KVCacheManagerV2 teardown on a thread without a CUDA context poisons the process. Remove these entries when the fix lands.
Dev Engineer Review
The change adds 44 attention-test waivers, all linked to NVBUG 6948011. This is a broad temporary test suppression; remove the waivers when the teardown fix lands.
QA Engineer Review
tests/integration/test_lists/waives.txtadds 44 skip entries for attention tests, including sparse attention, MLA, FlashInfer, and KV-cache manager tests. The waivers suppress these tests rather than change their behavior. Coverage verdict: needs follow-up; remove the waivers after the reported teardown fix lands. Test execution results were not provided.Per-File QA Perspective
tests/integration/test_lists/waives.txt: Adds 44 attention-test skip selectors linked to NVBUG 6948011. QA should verify the affected tests run again after the teardown fix lands.Description
