Move the field 'tk_rpc_status' so that we eliminate a 4 byte hole in the
structure.
For x86_64, this shrinks the size of the struct by 8 bytes.
'pahole' output before the change:
/* size: 232, cachelines: 4, members: 27 */
/* sum members: 222, holes: 1, sum holes: 4 */
/* sum bitfield members: 8 bits (1 bytes) */
/* padding: 5 */
/* last cacheline: 40 bytes */
'pahole' output after the change:
/* size: 224, cachelines: 4, members: 27 */
/* padding: 1 */
/* last cacheline: 32 bytes */

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
