The task
Running `stress-ng --sleep 0` causes the `scx_flash` scheduler to become unresponsive because tasks that frequently sleep and wake up generate excessive contention on the shared DSQ lock. A previous attempt to alleviate this by dispatching such tasks directly to the local DSQ was subsequently reverted: while it…
