This series tries to get rid of the damage created by sprinkling the network namespace cat poo all over rpc_pipefs and users. Instead of getting lost in a maze of notifiers and infrastructure build around it a cargo cult manner we revert to a slightly nicer version of the pre-namespace API. To do this we just have to create an in-kernel instance of rpc_pipefs that is mounted at network namespace creation so that all functions can operated on it. As-is this has one major downside: because the initial mount already grabs a reference to the network namespace we'll create a cyclic reference and will never free the network namespace. To get around this we'd need some way to only grab it once user mounts show up / disapear in the VFS. Given that the namespace kraken has infected various internal filesystem and will get more soon I suspect this problem is or will become generic and will need a proper solution anyway. Al, any good ideas how to deal with this? Most straight forward way would be to add a counter of user vfsmount to the superblock and methods when it goes to 1 and 0, but that seems a bit ugly. -- 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
