Grace-period initialization first processes any recent CPU-hotplug operations, and then initializes state for the new grace period. These two phases of initialization are currently not distinguished in debug prints, but the distinction is valuable in a number of debug situations. This commit therefore introduces two new values for ->gp_state, RCU_GP_ONOFF and RCU_GP_INIT, in order to make this distinction. 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.
