linux-stable.git/tools/testing/scatterlist/linux, branch linux-5.11.y Linux kernel stable tree tools/testing/scatterlist: Fix test to compile and run 2020-11-18T00:02:20+00:00 Maor Gottlieb maorg@nvidia.com 2020-11-15T12:06:23+00:00 ee415d73dcc24caef7f6bbf292dcc365613d2188 Add missing define of ALIGN_DOWN to make the test build and run. In addition, __sg_alloc_table_from_pages now support unaligned maximum segment, so adapt the test result accordingly.
