Subject: mds: to print the unknow type value
X-Git-Tag: v16.2.6~152^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=7b7840d5e351447ebdd48e017aaf65182970f930;p=ceph.git

mds: to print the unknow type value

Initialize the metric type when constructing the XXXPayload class,
and add one common base Payload class to simplify the code.

Fixes: https://tracker.ceph.com/issues/51113
Signed-off-by: Xiubo Li <xiubli@redhat.com>
(cherry picked from commit 562ba7877360226bbf09b33a9b0c5664c8d81c12)

Conflicts:
	src/include/cephfs/metrics/Types.h
- Fixed minor conflict when printing the "client_metric_type".
