Oleg is working on some patches which will permit us to cancel or wait upon a particular work_struct, rather than upon all pending work_structs. This will fix the problem where we accidentlly wait upon some unrelated work_struct which takes a lock which is related to one which we already hold. I hope. It'll be a bit tricky to implement: if some foreign work_struct is running right now, we cannot wait upon it - we must non-blockingly dequeue the work_struct which we want to kill before it gets to run. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
