Early /sbin/hotplug processes are a very good stress-test for unionfs.
Justin,
Compiling a kernel according to the latest trunk config, with unionfs,
but with "/sbin/hotplug" replaced with "" (the empty string) in
lib/kobject_uevent.c is also a good test case (because this eliminates
the stress). If that helps, the hang is definitely a unionfs bug.
This does not, however, fully replace or interfere with the DM test.
