Delay before device becomes availiable

[GoogleCodeExporter]

What steps will reproduce the problem?
1. run: modprobe compcache && mv /dev/compcache0 /dev/ramzswap0

What is the expected output? What do you see instead?
I expect to have a new device named /dev/ramzswap0. I actually get an error
claiming that /dev/compcache0 does not exist.


What version of the product are you using? On what operating system?
compcache-0.2 on Ubuntu Hardy


Please provide any additional information below.
sleep 1 seems to be enough to ensure that the device has been created.
However it would be nice if modprobe/insmod did not return until the device
has been created, as this avoids timing gotchas (sleep 0.01 is *sometimes*
enough).

This was basically udev issue. use_compcache.sh script in compcache-0.3 now 
makes
sure we do swapon only after device node is created (using udevadm settle).
