This commit adds each rcu_node structure's ->qsmask and "bBEG" output indicating whether: (1) There is a boost kthread, (2) A reader needs to be (or is in the process of being) boosted, (3) A reader is blocking an expedited grace period, and (4) A reader is blocking a normal grace period. This helps diagnose RCU priority boosting failures. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
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.
