    > Do u need this even for mandatory barriers whose semantics are not related to SMP at all ? I think you need them only for smb_*
    Yes I do.
    For example it is used to proceed access to our Global Interrupt Manager (GIM) when we want to make sure that driver of some device committed all read/writes before we are acknowledging the GIM.
    We are not falling to use "sync" since we prefer to have HW thread schedule in the meantime we wait for load/store to be done.

    - Noam
