kld regression

[Andriy Gapon]

The problem is as follows:
1. put udf_load="YES" in loader.conf
2. you can mount and unmount udf filesystems
3. you can kldunload udf if no udf filesystems are mounted
4. now mount udf fs while udf.ko is unloaded
5. udf is auto loaded and fs is mounted
6. unmount fs
7. try to kldunload udf
kldunload: can't unload file: Device busy
kernel message: kldunload: attempt to unload file that was loaded by the
kernel

Yeah, it was loaded by kernel indeed, but WTF - what is the difference
from manual/loader.conf loading and why I can not manage my modules as I
wish?
