From 9cd1447e6277bef335a3c50e3778e4593c9f0d3e Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Wed, 29 May 2019 18:02:44 +0100 Subject: [PATCH] binder: Replace "%p" with "%pK" for stable This was done as part of upstream commits fdfb4a99b6ab "8inder: separate binder allocator structure from binder proc", 19c987241ca1 "binder: separate out binder_alloc functions", and 7a4408c6bd3e "binder: make sure accesses to proc/thread are safe". However, those commits made lots of other changes that are not suitable for stable.
