Created attachment 256161 [details] the .config file I used When building the newest Linux 4.11.0 kernel, it failed with the following errors when "MODPOST vmlinux.o": ``` drivers/built-in.o:core.c:function lpfc_nvme_create_localport: error: undefined reference to 'nvme_fc_register_localport' drivers/built-in.o:core.c:function lpfc_nvme_destroy_localport: error: undefined reference to 'nvme_fc_unregister_remoteport' drivers/built-in.o:core.c:function lpfc_nvme_destroy_localport: error: undefined reference to 'nvme_fc_unregister_localport' drivers/built-in.o:core.c:function lpfc_nvme_register_port: error: undefined reference to 'nvme_fc_register_remoteport' drivers/built-in.o:core.c:function lpfc_nvme_unregister_port: error: undefined reference to 'nvme_fc_unregister_remoteport' drivers/built-in.o:core.c:function lpfc_nvmet_create_targetport: error: undefined reference to 'nvmet_fc_register_targetport' drivers/built-in.o:core.c:function lpfc_nvmet_destroy_targetport: error: undefined reference to 'nvmet_fc_unregister_targetport' drivers/built-in.o:core.c:function lpfc_nvmet_unsol_ls_event: error: undefined reference to 'nvmet_fc_rcv_ls_req' drivers/built-in.o:core.c:function lpfc_nvmet_unsol_fcp_event: error: undefined reference to 'nvmet_fc_rcv_fcp_req' ```
I ran into this today when I set CONFIG_SCSI_LPFC=y ... CONFIG_NVME_FC=m ... CONFIG_NVME_TARGET_FC=m One workaround is to set CONFIG_SCSI_LPFC=n And another workaround is to set CONFIG_SCSI_LPFC=y ... CONFIG_NVME_FC=y ... CONFIG_NVME_TARGET_FC=y While searching for a solution I found this: https://lkml.org/lkml/2017/3/21/308 I'm not sure that the suggested patch is the best fix, but something needs to be changed...
Created attachment 256235 [details] CONFIG_SCSI_LPFC patch to drivers/scsi/Kconfig Attached is another possible patch which makes it clear what is required to make CONFIG_SCSI_LPFC work and does not turn anything off.
