From 5d61e43b3975c0582003329d9de9d5e85abf5d33 Mon Sep 17 00:00:00 2001 From: Dan Williams <dan.j.williams@intel.com> Date: Tue, 27 Jun 2017 13:06:22 -0700 Subject: dax: remove default copy_from_iter fallback Require all dax-drivers to register a ->copy_from_iter() operation so that it is clear which dax_operations are optional and which must be implemented for filesystem-dax to operate.
