Applied (release notes conflict - but that's par for the course close to integration) Build each patch with meson (git rebase -x is awesome :) Ran unit tests: $ ioat_rawdev_probe(): Init 0000:00:04.0 on NUMA node 0 $ failed_enqueues: 0 successful_enqueues: 3300 copies_started: 3300 copies_completed: 3300 All seems fine to me; Series-Tested-by: Harry van Haaren <harry.van.haa...@intel.com>
