Alexander Motin 63297dfd4a Some improvements to GEOM MULTIPATH: ... - Implement "configure" command to allow switching operation mode of running device on-fly without destroying and recreation. - Implement Active/Read mode as hybrid of Active/Active and Active/Passive. In this mode all paths not marked FAIL may handle reads same time, but unlike Active/Active only one path handles write requests at any point in time. It allows to closer follow original write request order if above layers need it for data consistency (not waiting for requisite write completion before sending dependent write). - Hide duplicate messages about device status change. - Remove periodic thread wake up with 10Hz rate.
