    Subject[RFT PATCH 0/4] fix / cleanup async scsi scanning
    From
    Date
    Commit a7a20d10 "[SCSI] sd: limit the scope of the async probe domain"
    introduces a boot regression by moving sd probe work off of the global
    async queue. Using a local async domain hides the probe work from being
    synchronized by wait_for_device_probe()->async_synchronize_full().

    Fix this by teaching async_synchronize_full() to flush all async work
    regardless of domain, and take the opportunity to convert scsi scanning
    to async_schedule(). This enables wait_for_device_probe() to flush scsi
    scanning work.

    Lightly boot tested, Meelis does this fix your regression?

    Thanks for your help.
