Paolo Bonzini fc24908e7d blockjob: reimplement block_job_sleep_ns to allow cancellation ... This reverts the effects of commit 4afeffc857 ("blockjob: do not allow coroutine double entry or entry-after-completion", 2017-11-21) This fixed the symptom of a bug rather than the root cause. Canceling the wait on a sleeping blockjob coroutine is generally fine, we just need to make it work correctly across AioContexts. To do so, use a QEMUTimer that calls block_job_enter. Use a mutex to ensure that block_job_enter synchronizes correctly with block_job_sleep_ns.
