No, msleep sleeps (as its name suggests). The code that implements it is:
void msleep(unsigned int msecs)
{
unsigned long timeout = msecs_to_jiffies(msecs);
while (timeout) {
set_current_state(TASK_UNINTERRUPTIBLE);
timeout = schedule_timeout(timeout);
}
}

"Next the statesmen will invent cheap lies, putting the blame upon
the nation that is attacked, and every man will be glad of those
conscience-soothing falsities, and will diligently study them, and refuse
to examine any refutations of them; and thus he will by and by convince
himself that the war is just, and will thank God for the better sleep
he enjoys after this process of grotesque self-deception." -- Mark Twain
