There is duplicated code for initializing a nocache_read_request and also freeing the associated storage in certain cases. Create a set of helper functions that allocates and frees a nocache_read_request and its associated structures. afs_alloc_ncr allocates a nocache_read_request structure and if not UKERNEL, will allocate and initialize the associated uio and iovec structures. afs_free_ncr releases a noncache_read_request structure and the associated uio and iovec structures if not UKERNEL. Update locations that allocate/free nocache_read_request structures to use the new functions.

AFS is a distributed file system that enables users to share and access all of the files stored in a network of computers as easily as they access the files stored on their local machines. The file system is called distributed for this exact reason: files can reside on many different machines, but are available to users on every machine. OpenAFS 1.0 was originally released by IBM under the terms of the IBM Public License 1.0 (IPL10). For details on IPL10 see the LICENSE file in this directory. The current OpenAFS distribution is licensed under a combination of the IPL10 and many other licenses as granted by the relevant copyright holders. The LICENSE file in this directory contains more details, thought it is not a comprehensive statement. See INSTALL for information about building and installing OpenAFS on various platforms.
