Nitpick: GFP_KERNEL should be on the same line if there is enough space 
or aligned with &hwsim_netgroup_ida


Out of curiosity, how do you generate these patches?
(coccinelle should be the perfect tool for it, but I thought it would 
already deal with alignment)

Heh, this email address got me confused :) I guess you (Christophe) use
gmane and it's just some obfuscation done by gmane?

Yes, I use gname and thunderbird as a client. I also think that it is 
some obfuscation done by gname.

This kind of obfuscation is not done on all messages, and not done 
consistently on the message of the same ML. I don't know the rule that 
is applied.
