From cc03f19cfd45f44a75f0445c5be0073bbd3dda1c Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sun, 16 Feb 2020 15:10:33 -0500 Subject: ia64: csum_partial_copy_nocheck(): don't abuse csum_partial_copy_from_user() Just inline the call and use memcpy() instead of __copy_from_user() and note that the tail is precisely ia64 csum_partial().
