Cover letter [PATCH v3 0/2] add sysfs entry "patched" for each klp_object
I was debugging an issue that a livepatch appears to be attached, but actually not. It turns out that there is a mismatch in module name (abc-xyz vs. abc_xyz), klp_find_object_module failed to find the module. Add a sysfs entry for each klp_object, so that it is easier to debug such issues.
