I was backporting this to our ChromeOS kernels and our build test bot noticed that arch_smp_send_reschedule() didn't exist in older kernels. That's fine--I can always adjust this patch when backporting or cherry-pick extra patches, but it made me wonder. Is there a reason you chose to use arch_smp_send_reschedule() directly here instead of smp_send_reschedule()? I guess the only difference is that you're bypassing the tracing. Is that on purpose? Should we add a comment about it, or change this to smp_send_reschedule()? Thanks! -Doug _______________________________________________ Kgdb-bugreport mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/kgdb-bugreport
