Isn't mdelay(msecs) just a busy loop? http://kerneltrap.org/node/6857 Normally busy loops are used to syncronize with physical world results. For instance if you write to a device control register and per the spec. the status register is not valid for 5 msecs, then you would put a mdelay(5) between the write and the read.
