[opensuse-kernel] v4.13-rc1 module linking issue
Hi, I'm facing an error trying to locally build a custom kernel module: make -C /lib/modules/`uname -r`/build M=$PWD make[1]: Entering directory '/usr/src/linux-4.13.0-rc1-2.g9c198f2-obj/arm64/default' AR /home/andreas/lora/built-in.o CC [M] /home/andreas/lora/af_lora.o LD [M] /home/andreas/lora/lora.o CC [M] /home/andreas/lora/dev.o LD [M] /home/andreas/lora/lora-dev.o CC [M] /home/andreas/lora/sx1276.o CC [M] /home/andreas/lora/rn2483.o Building modules, stage 2.

Does the file in question exist? If there is, it's likely some race. If not, it's some missing dependency or such. FWIW, arch/arm64/kernel/ftrace-mod.S was added by commit e71a4e1bebaf7fd990efbdc04b38e5526914f0f1 arm64: ftrace: add support for far branches to dynamic ftrace Takashi

Despite the object is needed for modules build, we haven't packaged it. Hopefully fixed. thanks, -- js suse labs -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

Confirming fixed with today's kernel. Many thanks!
