From: Peng Liu <liupeng256@xxxxxxxxxx> [ Upstream commit bdd015f7b71b92c2e4ecabac689642cc72553e04 ] In function kunit_test_timeout, it is declared "300 * MSEC_PER_SEC" represent 5min. However, it is wrong when dealing with arm64 whose default HZ = 250, or some other situations. Use msecs_to_jiffies to fix this, and kunit_test_timeout will work as desired.
