Comment 6 for bug 1913188

Hi,

The particular test that is timing out actually is supposed to emit periodic output to stdout; it basically is running the test program from kernel commit b4a1b4f5047e4f54e194681125c74c0aa64d637d 100000 times and attempts to emit a count every 1000 iterations, writing to and flushing stdout.

The test itself spins up four threads that do keyctl_read() and keyctl_revoke(), to try to trigger a race condition in the kernel.

Is the test timeout a strict timeout, or is it not seeing forward progress via output to stdout?
I know in the kernel autotests stdout gets buffered in some way, so I could adjust the script to emit the counter to stderr instead, if that would help indicate that forward progress is being made.
