Description


if (split && con && con->has_features(CEPH_FEATUREMASK_RESEND_ON_SPLIT)) {
return RECALC_OP_TARGET_NEED_RESEND;
}

resending depends on con features, if con was just reset, its feature bits is empty, letting this op sneaks.
further more, if this op was resent finally after some new writes(it can happen because acting changed, con reset again..)
, causing out of order.

shall we move objecter resend logic from ms_handle_reset to ms_handle_connect?
