Both extended-quiescent-state entry and exit first update the nesting counter and then adjust the dyntick-idle state. This means that there are four states: (1) Both nesting and dyntick idle indicate idle, (2) Nesting indicates idle but dyntick idle does not, (3) Nesting indicates non-idle and dyntick idle does not, and (4) Both nesting and dyntick idle indicate non-idle. This commit simplifies the state space by eliminating #3, reversing the order of updates on exit from extended quiescent state. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
