I forgot 32bit arches might have 64bit alignment for u64
fields.
tcp_sock_write_txrx group does not contain pointers,
but two u64 fields. It is possible that on 32bit kernel,
a 32bit hole is before tp->tcp_clock_cache.
I will try to remember a group can be bigger on 32bit
kernels in the future.
With help from Vladimir Oltean.
Fixes: d2c3a7eb1a ("tcp: more struct tcp_sock adjustments")

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 reStructuredText 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.
