The keepalive timer fires every timeout/2 ms, but due to rounding errors and jitter, the host may decide not to send a keepalive at timeout/2. By the time the next timer fires, a full timeout period may have expired causing the device to be disconnected without ever having been sent a keepalive. Changing the keepalive threshold to timeout/3 ensures that at least one keepalive will be sent before a device is disconnected. The patch also updates the code to use msecs_to_jiffies consistently.
