CPUs are expected to report quiescent states when coming online and when going offline, and grace-period initialization is supposed to handle any race conditions where a CPU's ->qsmask bit is set just after it goes offline. This commit adds diagnostics for the case where an offline CPU nevertheless has a grace period waiting on it. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
