Subject: [PATCH 08/16] whpx nvmm: Drop useless migrate_del_blocker()
Date: Tue, 20 Jul 2021 14:54:00 +0200 [thread overview]
Message-ID: <20210720125408.387910-9-armbru@redhat.com> (raw)
In-Reply-To: <20210720125408.387910-1-armbru@redhat.com>
There is nothing to delete after migrate_add_blocker() failed. Trying
anyway is safe, but useless. Don't.
