I guess it's not really important, but this function might wait substantially
longer than requested. If you have CONFIG_HZ=100, msleep(1) will sleep for
at least 10 miliseconds. The correct way to sleep for up to a given amount
of time is to calculate the end time in jiffies, and use time_before() in
the loop condition.
