SUNRPC: create unix gid cache per network namespace v2: 1) fixed silly usage of template cache as a real one (this code left from static global cache for all) This patch makes unix_gid_cache cache detail allocated and registered per network namespace context. Thus with this patch unix_gid_cache contents for network namespace "X" are controlled from proc file system mount for the same network namespace "X".

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>

SUNRPC: pipefs per-net operations helper introduced During per-net pipes creation and destruction we have to make sure, that pipefs sb exists for the whole creation/destruction cycle. This is done by using special mutex which controls pipefs sb reference on network namespace context. Helper consists of two parts: first of them (rpc_get_dentry_net) searches for dentry with specified name and returns with mutex taken on success. When pipe creation or destructions is completed, caller should release this mutex by rpc_put_dentry_net call.

SUNRPC: make SUNPRC clients list per network namespace context This patch moves static SUNRPC clients list and it's lock to sunrpc_net structure. Currently this list is used only for debug purposes. But later it will be used also for selecting clients by networks namespace on PipeFS mount/umount events. Per-network namespace lists will make this faster and simplier. Note: client list is taken from "init_net" network namespace context in rpc_show_tasks(). This will be changed some day later with making SUNRPC sysctl's per network namespace context.

SUNRPC: move rpcbind internals to sunrpc part of network namespace context This patch makes rpcbind logic works in network namespace context. IOW each network namespace will have it's own unique rpcbind internals (clients and friends) required for registering svc services per network namespace.
