Subject[PATCH v2 0/4] net_dma removal, and dma debug extension
From
Date
Follow up patches to 77873803363c "net_dma: mark broken" to remove
net_dma bits and provide debug infrastructure to flag other
get_user_pages() vs dma instances that might violate the dma api.

Will takes this through the dmaengine tree once acked.

Changes since v1 [1]:

1/ net_dma removal patch has been expanded to revert other
net_dma induced changes.

2/ updated the debug_dma_assert_idle() api to be gated on
CONFIG_DMA_VS_CPU_DEBUG

---

Dan Williams (4):
net_dma: simple removal
net_dma: revert 'copied_early'
net: make tcp_cleanup_rbuf private
dma debug: introduce debug_dma_assert_idle()
