Hello Paolo,

Hello Jens,
Recently Joseph Qi identified races between the block cgroup code and request
queue initialization and cleanup. This patch series address these races. Please
consider these patches for kernel v4.17.
Thanks,

This removes the dependency on interrupts to wake up task. Set task
state as TASK_RUNNING, if need_resched() returns true,
while polling for IO completion.
Earlier, polling task used to sleep, relying on interrupt to wake it up.
