X-Git-Tag: v15.1.0~1715^2 X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=d411ee26fb2f6cbe610f8bbc81b777cf28d839c2;p=ceph.git bluestore/bdev: initialize size when creating object. The other partss of the struct are initialized by their ctors. Only for unint_64 there is no ctor. Otherwise ceph-dencoder tests will fail in comparing the exported output.
