Add lockdep annotations for the transaction states that have wait events; 1) TRANS_STATE_COMMIT_START 2) TRANS_STATE_UNBLOCKED 3) TRANS_STATE_SUPER_COMMITTED 4) TRANS_STATE_COMPLETED The new macros introduced here to annotate the transaction states wait events have the same effect as the generic lockdep annotation macros. With the exception of the lockdep annotation for TRANS_STATE_COMMIT_START the transaction thread has to acquire the lockdep maps for the transaction states as reader after the lockdep map for num_writers is released so that lockdep does not complain.

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.
