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.

Does this need a:

Because I have seen patch
df3c30f6e904 ("staging: lustre: replace direct HZ access with kernel APIs").
Here, both "msecs_to_jiffies(MSEC_PER_SEC)" and "300 * HZ" is ok for me.
