sbt is the time in the future that the tsleep_sbt() is expected to be completed at. sbtt is the current time. Depending on the precision with sysctl kern.timecounter.alloweddeviation the start time may be incremented by tc_tick_sbt. The same increment is needed for the current time of sbtt before calculating the difference. The impact of missing this increment is that rmtp may increase by one tc_tick_sbt on every early [EINTR] return. If the same struct is passed in for rqtp as rmtp this can result in rqtp effectively incrementing by tc_tick_sbt and sleeping longer than originally intended. This problem was introduced in r247797.
