Why do you think this should be a module ? Is it because, it is lying here among others '=m' ? Or you have some other reasoning ? like it is for qcom specific soc and can not be used outside ? but that is not true for all configs mentioned here. The reason behind making it as '=y' was, to collect information from core kernel data structure as well as the information like percpu data, run queue, irq stat kind of information on kernel crash on a target running some perf configuration(android phone). -- Mukesh > > Best regards, > Krzysztof >

Because we want and insist on everything being a module. That's the generic rule. There are exceptions, so if this justifies being an exception, please bring appropriate arguments. > > Or you have some other reasoning ? like it is for qcom specific > soc and can not be used outside ? but that is not true for > all configs mentioned here. > > The reason behind making it as '=y' was, to collect information from > core kernel data structure as well as the information like percpu data, > run queue, irq stat kind of information on kernel crash on a target > running some perf configuration(android phone). I don't understand why =m stops you from all that. What's more, I don't understand why do you refer to the Android here. This is a development and debugging Linux defconfig, not Android reference config for vendors... Best regards, Krzysztof

You allow it to be a module in patch #4, so I think you solved it, right? Otherwise it could not be a module? Anyway, where do you use kallsyms_lookup_name()? I cannot find it in your patch.

Previous patches add the Qualcomm minidump driver support, so lets enable minidump config so that it can be used by kernel clients. Signed-off-by: Mukesh Ojha <quic_mojha@quicinc.com> --- arch/arm64/configs/defconfig | 1 + 1 file changed, 1 insertion(+)
