Hello,
The 1st patch moves module_put() to release handler of klp_patch kobject.
The 2nd patch changes to free klp_patch and other kobjects without klp_mutex.
The 3rd patch switches to synchronous kobject release for klp_patch.
V4: - add freeing klp_patch after klp_enable_patch() returns, since patch still can be freed there in case of ->replace is set
V3: - one line fix on check of list_empty() in enabled_store(), 3/3
V2: - remove enabled attribute before deleting this klp_patch kobject, for avoiding deadlock in deleting me
Ming Lei (3): livepatch: remove 'struct completion finish' from klp_patch livepatch: free klp_patch object without holding klp_mutex livepatch: free klp_patch object synchronously
