SUNRPC: put pipefs superblock link on network namespace
We have modules (like, pNFS blocklayout module) which creates pipes on rpc_pipefs. Thus we need per-net operations for them. To make it possible we require appropriate super block. So we have to put sb link on network namespace context. Note, that it's not strongly required to create pipes in per-net operations. IOW, if pipefs wasn't mounted yet, that no sb link reference will present on network namespace and in this case we need just need to pass through pipe creation. Pipe dentry will be created during pipefs mount notification. Signed-off-by: Stanislav Kinsbursky <skinsbursky@parallels.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
