rpc_queue_upcall - queue an upcall message to userspace
int rpc_queue_upcall(struct rpc_pipe
*pipe, struct rpc_pipe_msg *msg);
- upcall pipe on which to queue given message
- message to queue
Call with an inode created by rpc_mkpipe to queue an upcall. A userspace process may then later read the upcall by performing a read on an open file for this inode. It is up to the caller to initialize the fields of msg (other than msg->list) appropriately.
