are you doing some work in that direction? I was thinking to add a new osenv
interface (someting like oskit_osenv_softirq...) to register/unregister,
mask/unmask and mark/unmark a software interrupt. mark_bh(...) and the like
would be redirected to this interface through glue code, while the actual
dispatching of the software interrupt would be done by
base_softintr_handle. Do you think it is a viable solution? I am sure I am
missing something, otherwise you would have already done it...

Another question: will asyncio interface ever be supported for linux block
devices?

Thanks for your attention,
