This allows for drivers to utilize the optimization of merging contiguous pages without a need to pre allocate all the pages and hold them in a very large temporary buffer prior to the call to SG table initialization. The last patch changes the Infiniband core to use the new API. It removes duplicate functionality from the code and benefits from the optimization of allocating dynamic SG table from pages. In huge pages system of 2MB page size, without this change, the SG table would contain x512 SG entries. ==================== * branch 'dynamic_sg': RDMA/umem: Move to allocate SG table from pages lib/scatterlist: Add support in dynamic allocation of SG table from pages tools/testing/scatterlist: Show errors in human readable form tools/testing/scatterlist: Rejuvenate bit-rotten test --- 16e7483e6f02973972f832b18042fd6c45fe26c0
