From 5ea75ae6ae60d13dfa35fd5d2e2a81824cba6662 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Tue, 18 Feb 2020 17:30:05 -0500 Subject: [PATCH] user_regset_copyout_zero(): use clear_user() that's the only caller of __clear_user() in generic code, and it's not hot enough to bother with skipping access_ok().
