Alexander Lochmann d699ae4fc2 ext4: updated locking documentation for journal_t
Some members of transaction_t are allowed to be read without any lock
being held if consistency doesn't matter.  Based on LockDoc's
findings, we extended the locking documentation of those members.
Each one of them is marked with a short comment: "no lock for quick
racy checks".

README

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.
