Subject: [PATCH v1 1/2] kasan: free allocated shadow memory on MEM_CANCEL_OFFLINE
Date: Tue, 22 May 2018 11:55:14 +0200 [thread overview]
Message-ID: <20180522095515.2735-2-david@redhat.com> (raw)
In-Reply-To: <20180522095515.2735-1-david@redhat.com>
We have to free memory again when we cancel onlining, otherwise a later
onlining attempt will fail.
