Date: Tue,  1 Mar 2022 19:30:10 +0800	[thread overview]
Message-ID: <20220301113015.498041-3-xiubli@redhat.com> (raw)
In-Reply-To: <20220301113015.498041-1-xiubli@redhat.com>

From: Xiubo Li <xiubli@redhat.com>

We should skip the extra memories which are from the higher version
just likes the libcephfs client does.
