From 46c5a0113f843be5c55b1c40dd486538891156d4 Mon Sep 17 00:00:00 2001 From: Josh Poimboeuf <jpoimboe@redhat.com> Date: Mon, 13 Feb 2017 19:42:30 -0600 Subject: [PATCH] livepatch: create temporary klp_update_patch_state() stub Create temporary stubs for klp_update_patch_state() so we can add TIF_PATCH_PENDING to different architectures in separate patches without breaking build bisectability.
