The vd->node is removed from the lists when the transfer started so the vchan_get_all_descriptors() will not find it. This results memory leak.Acked-by: Stephen Warren <redacted> (I'm just assuming the explanation makes sense and is correct; more of a not-a-NAK so it doesn't look like a lack of response!)
I can not debug the bcm2835-dma driver, but the exact same pattern existed in edma and omap-dma driver and they both leaked the edesc in a same predictable fashion. I just checked the virt-dma users and sent the fixes for the ones which had the same flow of events. -- P?ter
