Greg, there were 3 specific complaints from you:

1. Given that this is a static function, there's no need for these
asserts, right?  Please send a follow-on patch removing all BUG_ON()
calls from these files, it's not acceptable to crash a user's box from
a driver that is handling parameters you are feeding it.

2. You obviously didn't run checkpatch on this file

3. This line causes sparse to complain.  The odds that userspace knows
what gcc is using for bool is pretty low.

Given the fact that the series addresses all 3 I fail to understand why
you would be grumpy.

Anyway, since there vsock has not been reviewed yet we are OK with
postponing this patch series till 3.9.

Thanks,
Dmitry

Sorry, yes :)

 I think that even if we had a special directory for vmci having network

 directory would contain vmci and the balloon driver (vsock will go into
 net/).  Given that balloon is already in drivers/misc it looked like
 obvious place for VMCI as well.

I agree that the individual drivers should go in the subsystem area,
it's this hypervisor bus core type code that I'm questioning.  Right
now every hypervisor is putting that logic in a different place in the

drivers/platform/hyperv
drivers/platform/olpc
drivers/platform/vmware
drivers/platform/xen
drivers/platform/x86

But really we'd like to get VMCI into mainline first and move to a new

   net/).  Given that balloon is already in drivers/misc it looked like
   obvious place for VMCI as well.
  
  I agree that the individual drivers should go in the subsystem area,
  it's this hypervisor bus core type code that I'm questioning.  Right
  now every hypervisor is putting that logic in a different place in the
  kernel, having some consistency here would be nice.
 
 Hmm, I wonder if miscellaneous and core hypervisor drivers should end
 up in drivers/platform:
 
   drivers/platform/hyperv
   drivers/platform/olpc
   drivers/platform/vmware
   drivers/platform/xen
   drivers/platform/x86

That makes sense to me, nice.

 But really we'd like to get VMCI into mainline first and move to a new
 place later if such a better place is found.

Heh, no one wants to fight for something to help everyone out, they just
want their own code accepted :)

No, this is more about finding a person who would be maintaining it and
thus would review our code. For now we got you tagged and do not want to
let go of you :P

Or should we maintain our own stuff and have Linus pull it directly,
like Xen guys appear to be doing? Really, moving it is not an issue for
us.

Thanks,
Dmitry

No, I don't mind doing some of the review, and getting it to Linus to
start with, but over time, having you all be the owners and push stuff
directly to him is fine with me.

So I agree, for now, let's leave it as-is.
