Hi Vinod and Maxime, This very same patch was already submitted in [1]. It enables the reuse of transfers through their lifetime. I added to this serie the documentation patch Maxime has been commenting, as it is tighly linked. The "RESEND" is a bit zealous as the documentation patch was fixed according to Maxime's first 2 comments. Cheers. -- Robert [1] https://lkml.org/lkml/2015/3/21/230 Robert Jarzmik (2): dmaengine: virt-dma: don't always free descriptor upon completion Documentation: dmaengine: document DMA_CTRL_ACK Documentation/dmaengine/provider.txt | 11 ++++++----- drivers/dma/virt-dma.c | 19 +++++++++++++------ drivers/dma/virt-dma.h | 13 ++++++++++++- 3 files changed, 31 insertions(+), 12 deletions(-) -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe dmaengine" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
