We introduce the same handling for potential data races with the 'fully_established' flag in subflow as previously done for msk->fully_established. Additionally, we make a crucial change: convert the subflow's 'fully_established' from 'bit_field' to 'bool' type. This is necessary because methods for avoiding data races don't work well with 'bit_field'. Specifically, the 'READ_ONCE' needs to know the size of the variable being accessed, which is not supported in 'bit_field'. Also, 'test_bit' expect the address of 'bit_field'.

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.
