</div></div>It seems that you have enabled CONFIG_LUSTRE_FS in your local kernel<br>
config which would then define CONFIG_LNET_MAX_PAYLOAD on its own. The<br>
easy workaround is to disable in-kernel client in your kernel and<br>
rebuild.<br>
I am not sure if it makes sense to support such use case as there<br>
would be two sets of client modules for the same kernel.<br>
<br>
Cheers,<br>
