While doing my recent work on the generic smp function calls I noticed that smp_call_function_single without the wait flag can't work, as it allocates struct call_single_data on stack, and without the wait flag will happily return before the IPI has been executed.
This affects the following callers: arch/ia64/kernel/mca.c:mca_cpu_callback() arch/ia64/kernel/smpboot.c:ia64_sync_itc() arch/x86/kernel/kvm.c:kvm_cpu_notify() arch/x86/oprofile/nmi_int.c:oprofile_cpu_notifier() arch/x86/pci/amd_bus.c:amd_cpu_notify() drivers/staging/octeon/ethernet-rx.c:cvm_oct_enable_one_cpu() kernel/stop_machine.c:stop_two_cpus() It would be good to get these fixed so that we could remove the parameter. Either convert them to wait, or use a preallocated call_single_data and __smp_call_function_single. After that I'd like to remove the wait argument to prevent further abuses. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
