Bug in kmem_cache_create with duplicate names

[Steven Rostedt <rostedt@goodmis.org>]

Is it really necessary to BUG on creating a cache with a duplicate name?
Wouldn't it just be better to fail the create. The reason I mentioned
this is that I was writing some modules and after doing a cut and paste,
I forgot to change a name of a cache that was created by one module and
I used it in another existing module.  So you can say that it was indeed
a bug, but did it really need to crash my machine?  I aways check the
return codes in my modules, and I would have figured it out why it
failed, but I didn't expect a simple module to crash the machine the way
it did.  Well anyway it did definitely show me where my bug was.

Thanks,
