Kaike Wan a25ce4270b IB/rdmavt: Setting of QP timeout can overflow jiffies computation ... Current computation of qp->timeout_jiffies in rvt_modify_qp() will cause overflow due to the fact that the input to the function usecs_to_jiffies is only 32-bit ( unsigned int). Overflow will occur when attr->timeout is equal to or greater than 30. The consequence is unnecessarily excessive retry and thus degradation of the system performance. This patch fixes the problem by limiting the input to 5-bit and calling usecs_to_jiffies() before multiplying the scaling factor.
