I loaded the patches on my ppc64 box and they worked fine after I fixed a compile
bug. The attached patch fixes the compile bug and changes the call_usermodehelper
call in kset_hotplug to call_usermodehelper_async.
yup, thanks. I've changed the patch in my tree so that we always perform
the fully-async operation if call_usermodehelper() is passed "wait=0". It
gets the new code some more testing and keeps the kernel API simpler.
