…ernel BugLink: https://bugs.launchpad.net/bugs/2134960 With this change, the NVMe and NVMeoF driver would be enabled to support GPUDirectStorage(GDS). NVMe driver introduced a way to use the blk_rq_dma_map API to DMA map requests instead of scatter gather lists. With these changes, GDS path also adopts a similar framework where we introduce blk based APIs(nvfs_blk_rq_dma_map_iter_start and nvfs_blk_rq_dma_map_iter_next) to map a DMA request. The NVMeoF path remains the same as previous releases. Signed-off-by: Sourab Gupta <sougupta@nvidia.com> Reviewed-by: Kiran Modukuri <kmodukuri@nvidia.com>
