This commit landed in perf/core, but is gone now (the rest of > patches is still there). Any idea what happened? Yeah, I'm getting this build failure: kernel/events/uprobes.c:1158:9: error: implicit declaration of function ‘synchronize_rcu_tasks_trace’; did you mean ‘synchronize_rcu_tasks’? [-Werror=implicit-function-declaration] on x86-64 defconfig, when applied to today's perf/core. Thanks, Ingo
