Hi, I'm trying to kpatch to my own module, which is built as an out-of-tree module. I've test doit.sh in test/testmod in github. But the test script failed since it uses an very old synopsis format which only give 4 args to create-diff-object, which it requires 7 args. I've borrowed some code from kpatch-build to fix the create-diff-object call and generate the final kpatch-patch.ko. But it failed to be loaded by kpatch. dmesg shows: "kpatch: can't set ftrace filter at address 0xffffffffa0423000". kpatch succeed when I included the testmod_drv.c in kernel tree and generate .ko through kpath-build. But this method doesn't suit for my external module. Can anyone fix the test/testmod sample or give me an guide on how to kpatch an External module ?
