Subject: [PATCH V3 0/3] livepatch: cleanup kpl_patch kobject release
Date: Mon, 1 Nov 2021 19:25:45 +0800 [thread overview]
Message-ID: <20211101112548.3364086-1-ming.lei@redhat.com> (raw)
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.
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
