msecs_to_jiffies() is implemented using tvtohz(9), which always returns a
positive value since it adds the current tick to its result. This differs from the behaviour in Linux, whose implementation does not add the extra tick, so subtract the extra tick in the OFED compat layer implementation. This addresses some incorrect handling of IB MAD timeouts, since some IB code depends on msecs_to_jiffies(0) returning 0. MFC after: 1 week Sponsored by: EMC / Isilon Storage Division
