Subject[PATCH v4 0/8] SUNRPC: make rpcbind clients allocated and destroyed dynamically
1) creation and destruction on rpcbind clients now depends on service program
versions "vs_hidden" flag.

This patch is required for further RPC layer virtualization, because rpcbind
clients have to be per network namespace.
To achive this, we have to untie network namespace from rpcbind clients sockets.
The idea of this patch set is to make rpcbind clients non-static. I.e. rpcbind
clients will be created during first RPC service creation, and destroyed when
last RPC service is stopped.
With this patch set rpcbind clients can be virtualized easely.

The following series consists of:


Stanislav Kinsbursky (8):
SUNRPC: introduce helpers for reference counted rpcbind clients
SUNRPC: use rpcbind reference counting helpers
SUNRPC: introduce svc helpers for prepairing rpcbind infrastructure
SUNRPC: setup rpcbind clients if service requires it
SUNRPC: cleanup service destruction
NFSd: call svc rpcbind cleanup explicitly
SUNRPC: remove rpcbind clients creation during service registering
SUNRPC: remove rpcbind clients destruction on module cleanup
