This patch adds a mandatory fileops param to relayfs_create_file() and exports that function so that clients can use it to create files defined by their own set of file operations, in relayfs. The purpose is to allow relayfs applications to create their own set of 'control' files alongside their relay files in relayfs rather than having to create them in /proc or debugfs for instance. relayfs_create_file() is also used by relay_open_buf() to create the relay files for a channel. In this case, a pointer to relayfs_file_operations is passed in, along with a pointer to the buffer associated with the file.
