Subject: [PULL 12/30] migration: add savevm_state_handler_remove()
Date: Tue, 14 Jan 2020 12:39:08 +0100 [thread overview]
Message-ID: <20200114113926.3556-13-quintela@redhat.com> (raw)
In-Reply-To: <20200114113926.3556-1-quintela@redhat.com>
From: Scott Cheloha <cheloha@linux.vnet.ibm.com>
Create a function to abstract common logic needed when removing a
SaveStateEntry element from the savevm_state.handlers queue.
For now we just remove the element. Soon it will involve additional
cleanup.
