Some of the warning labels used in the LKMM are unfortunately ambiguous. In particular, the same warning is used for both an unmatched rcu_read_lock() call and for an unmatched rcu_read_unlock() call. Likewise for the srcu_* equivalents. Also, the warning about passing a wrong value to srcu_read_unlock() -- i.e., a value different from the one returned by the matching srcu_read_lock() -- talks about bad nesting rather than non-matching values. Let's update the warning labels to make their meanings more clear.

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.
