From 5904122c46581a5ccee54a51ef07e0d891fd7aef Mon Sep 17 00:00:00 2001 From: Al Viro Date: Tue, 18 Feb 2020 14:26:32 -0500 Subject: take the dummy csum_and_copy_from_user() into net/checksum.h now that can be done conveniently - all non-trivial cases have _HAVE_ARCH_COPY_AND_CSUM_FROM_USER defined, so the fallback in net/checksum.h is used only for dummy (copy_from_user, then csum_partial) implementation. Allowing us to get rid of all dummy instances, both of csum_and_copy_from_user() and csum_partial_copy_from_user().
