a148866489fb ("sched: Replace rq::wake_list")
added
BUILD_BUG_ON(offsetof(struct task_struct, wake_entry_type) - offsetof(struct task_struct, wake_entry) !=
offsetof(struct __call_single_data, flags) - offsetof(struct __call_single_data, llist));
in kernel/smp.c. This seems to be failing - at least for gcc-8 (I
haven't seen any failures in my linux-next testing).
The pending-fixes branch in linux-next isjust Linus' tree plus the
branches of fixes for Linus' tree.
