Does this means, that I have to fix patch "SUNRPC: handle RPC > client pipefs dentries by network namespace aware routine" to make it able to > bisect? What I mean is that currently, I have various ways to Oops the kernel when I apply "SUNRPC: handle RPC client pipefs dentries by network namespace aware routine" before all these other followup patches are applied. One way to could fix this, might be to add dummy versions of rpc_pipefs_notifier_register()/unregister() so that "NFS: idmap PipeFS notifier introduced" and the other such patches can be applied without compilation errors or Oopses before the "handle RPC client pipefs dentries..." patch is applied. The latter could then enable the real rpc_pipefs_notifier_register()/.... The point is to not have these patches add _known_ bugs to the kernel at any point, so that someone who is trying to track down an unknown bug via "git bisect" doesn't have to also cope with these avoidable issues... -- Trond Myklebust Linux NFS client maintainer NetApp Trond.Myklebust@xxxxxxxxxx www.netapp.com -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
