Hi Andrew,

The 2.6.23-rc6-mm1build fails at

This seems to be occuring across a number of the powerpc systems we test
with.  That driver is a power dynamic lpar IO partitioning driver.

Relevant Cc: added.
    

That's because somebody is breaking sysfs/kobject interfaces without
fixing all users :-) (Fair enough... it's just that we need to make sure
whoever takes care of that driver nowadays is aware of the breakage).

Ben.
  

Hi Andrew,

Using the kobject_set_name function to set the kobject k_name.
