Subject: Re: [PATCH net-next] netlink: add spaces around '&' in
 netlink_recvmsg()

This in itself is not a sufficient justification to touch code that
pre-dates the git era.

IMHO '&' without spaces around it is particularly hard to read, and 
the code is actively used, which makes the change worth considering.

But I'm not sure why you decided to fix recvmsg but not sendmsg.

Please provide a better commit message.
