I was considering to change the dma_fence semantics so thatThat's not going to fly. As soon as you are dealing with device drivers
dma_fence_signal() could only be called from the interrupt contexts of
devices and then put a big fat WARN_ON(!in_interrupt()) in there.
It's a sledgehammer, but as far as I can see the only thing which might
help. Opinions?
that use IRQ threads, either voluntarily or even involuntarily on RT
kernels, the dma_fence_signal will be from process context.
