Subject: rgw: fix for uninitialized oldest_gen/latest_gen
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=aec6f86219f5ff9ee7884734b83178f4ee9d4f2e;p=ceph.git

rgw: fix for uninitialized oldest_gen/latest_gen

when data sync queries RGWOp_BILog_Info from an un-upgraded gateway, it
doesn't include the oldest_gen/latest_gen fields. so initialize these
variables to 0 by default
