kernel mode multi-threaded stress test - hang in bpf_object__load

[dv-msft]

Describe the bug

Running the native_load_attach_detach_unload_random_v4_test from the kernel mode stress test suite causes the test application to hang.

OS information

No response

Steps taken to reproduce bug

Run the kernel mode multi-threaded stress test with the following command line (Note the 1 (one) minute runtime):
.\ebpf_stress_tests_km -tt=32 -td=1 -erd=1000 native_load_attach_detach_unload_random_v4_test

Expected behavior

The test should pass successfully and terminate after one minute.

Actual outcome

The test hangs and does not terminate after the specified test duration. While there can be some unavoidable variation in the actual runtime (generally in range of 10 - 30 seconds), the test does not terminate even after 3 minutes.

_While not 100 % reproducible, this failure is very frequent.

The hang is seen in bpf_object__load() in the stack trace of the blocked thread:
