SYNOPSIS

struct dentry * rpc_mkpipe_dentry(struct dentry * parent, const char * name, void * private, struct rpc_pipe * pipe);

ARGUMENTS

parent

dentry of directory to create new "pipe" in

name

name of pipe

private

private data to associate with the pipe, for the caller's use

pipe

rpc_pipe containing input parameters

DESCRIPTION

Data is made available for userspace to read by calls to rpc_queue_upcall. The actual reads will result in calls to ops->upcall, which will be called with the file pointer, message, and userspace buffer to copy to.

Writes can come at any time, and do not necessarily have to be responses to upcalls. They will result in calls to msg->downcall.

The private argument passed here will be available to all these methods from the file pointer, via RPC_I(file_inode(file))->private.
