Hi @lulinqing , did you load kpatch.ko first?
from kpatch.
hi @jpoimboe , thanks for reminding... Seems I failed to load kpatch.ko because of some reason during the upgrade from fc19~fc20 ( issue #86 ) and I didn't notice that.
$ ls /usr/local/lib/modules/$(uname -r)/kpatch/kpatch.ko
/usr/local/lib/modules/3.13.6-200.fc20.x86_64/kpatch/kpatch.ko
$ sudo insmod /usr/local/lib/modules/$(uname -r)/kpatch/kpatch.ko
insmod: ERROR: could not insert module /usr/local/lib/modules/3.13.6-200.fc20.x86_64/kpatch/kpatch.ko: Invalid module format
$ dmesg | tail
...
[60868.408750] kpatch: version magic '3.13.6-100.fc19.x86_64 SMP mod_unload ' should be '3.13.6-200.fc20.x86_64 SMP mod_unload '
I do re-compiled the kpatch core module and re-installed via make && sudo make install
. But apparently it's not a clean one.

Yeah, if you don't always do a make clean after a kernel update then the core module can get out of date.
I just fixed it with #88. It should be fixed now if you do a make && sudo make install
with the latest master.

Thanks @jpoimboe , that sounds great.
Everything went well now after with a correct kpatch.ko loaded.

Ok good!
