David, could you please advise how to identify net namespace in kernel messages? In OpenVz we got many requests from host admins, they need to understand which container triggered the message. In such cases we have added our custom Container Id, but mainline lacks it. I expected that mainline can use net pointer for such purposes, nfsd does it for example: NFSD: starting 90-second grace period (net ffff880e307fe240) Now you recommend do not use net pointer. However could you please advise some alternative?
