SUNRPC: pass buffer size to svc_sock_names()
Adjust the synopsis of svc_sock_names() to pass in the size of the output buffer. Add a documenting comment. This is a cosmetic change for now. A subsequent patch will make sure the buffer length is passed to one_sock_name(), where the length will actually be useful. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.
