Merge branch 'sg_nents' into rdma.git for-next
From Maor Gottlieb ==================== Fix the use of nents and orig_nents in the sg table append helpers. The nents should be used by the DMA layer to store the number of DMA mapped sges, the orig_nents is the number of CPU sges. Since the sg append logic doesn't always create a SGL with exactly orig_nents entries store a total_nents as well to allow the table to be properly free'd and reorganize the freeing logic to share across all the use cases. ==================== Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> * 'sg_nents': RDMA: Use the sg_table directly and remove the opencoded version from umem lib/scatterlist: Fix wrong update of orig_nents lib/scatterlist: Provide a dedicated function to support table append
