From c811af767e61a3df7bd844b49812d85a9b910aa3 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Mon, 10 Sep 2018 16:36:10 -0500 Subject: [PATCH] anv/so_memcpy: Don't consider src/dst_offset when computing block size The only thing that matters is the size since we never specify any offsets in terms of blocks.
