module_put() is currently never called in klp_complete_transition() when klp_force is set. As a result, we might keep the reference count even when klp_enable_patch() fails and klp_cancel_transition() is called. This might give the impression that a module might get blocked in some strange init state. Fortunately, it is not the case. The reference count is ignored when mod->init fails and erroneous modules are always removed. Anyway, this might be confusing. Instead, this patch moves the global klp_forced flag into struct klp_patch. As a result, we block only modules that might still be in use after a forced transition. Newly loaded livepatches might be eventually completely removed later. It is not a big deal. But the code is at least consistent with the reality.
