Subject: [PATCH V2 0/3] livepatch: cleanup kpl_patch kobject release

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.


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
