SUNRPC: New xdr_streams XDR decoder API

2010-12-16T17:37:25+00:00

Now that all client-side XDR decoder routines use xdr_streams, there
should be no need to support the legacy calling sequence [rpc_rqst *,
__be32 *, RPC res *] anywhere.  We can construct an xdr_stream in the
generic RPC code, instead of in each decoder function.

This is a refactoring change.  It should not cause different behavior.

SUNRPC: New xdr_streams XDR encoder API

2010-12-16T17:37:25+00:00

Now that all client-side XDR encoder routines use xdr_streams, there
should be no need to support the legacy calling sequence [rpc_rqst *,
__be32 *, RPC arg *] anywhere.  We can construct an xdr_stream in the
generic RPC code, instead of in each encoder function.

Also, all the client-side encoder functions return 0 now, making a
return value superfluous.  Take this opportunity to convert them to
return void instead.

This is a refactoring change.  It should not cause different behavior.

SUNRPC: Fix a race in rpc_info_open

2010-09-12T23:55:25+00:00

There is a race between rpc_info_open and rpc_release_client()
in that nothing stops a process from opening the file after
the clnt->cl_kref goes to zero.

Fix this by using atomic_inc_unless_zero()...

SUNRPC: Move remaining RPC client related task initialisation into clnt.c

2010-08-04T12:54:07+00:00

Now that rpc_run_task() is the sole entry point for RPC calls, we can move
the remaining rpc_client-related initialisation of struct rpc_task from
sched.c into clnt.c.

Also move rpc_killall_tasks() into the same file, since that too is
relative to the rpc_clnt.

SUNRPC: The function rpc_restart_call() should return success/failure

2010-08-04T02:06:44+00:00

Both rpc_restart_call_prepare() and rpc_restart_call() test for the
RPC_TASK_KILLED flag, and fail to restart the RPC call if that flag is set.

This patch allows callers to know whether or not the restart was
successful, so that they can perform cleanups etc in case of failure.
