But now cuse_dev could be NULL. At very least, destroy_dev() should check that the cdev node was created.

It is checked already in cuse_kern_uninit(), no?

	if (cuse_dev != NULL)
		destroy_dev(cuse_dev);

I guess we could also make cuse_kern_init() return an int and propagate this back to cuse_modevent(), if needed. What do you think?

Sorry, ok. But if you cannot fail the module load, perhaps the printf() below should indicate a failure to create /dev/cuse instead of the path.
