Question is if you really want to do it this way? See usually exporters try to avoid blocking such functions.
Yes, it has to be this way, revoke is a synchronous user space triggered operation around things like FLR or device close. We can't defer it into some background operation like pm.
Yeah, but you only need that in a couple of use cases and not all.
Not all, that is why the dma_buf_attach_revocable() is there to distinguish this case from others.
