Subject: msg/async/ProtocolV2: cast usec to double when converting from nsec
X-Git-Tag: v17.1.0~728^2
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=8af0d76ca35fbc1d0ac13cd56180256019ff26c3;p=ceph-ci.git

msg/async/ProtocolV2: cast usec to double when converting from nsec

to be consistent with the same logic in V1, and more importantly, it is
