The rcu_data structure's ->gpwrap indicator is currently reset only when the CPU in question detects a new grace period. This is in theory sufficient because any CPU that has been out of action for long enough that its ->gpwrap indicator is set is guaranteed to see both the end of an old grace period and the start of a new one. However, the current code leaves a short window during which the ->gpwrap indicator has been reset but the corresponding ->gp_seq counter has not yet been brought up to date. This is harmless because interrupts are disabled, but it is likely to (at the very least) cause confusion. This commit therefore moves the resetting of ->gpwrap to follow the updating of ->gp_seq. While in the area, it also resets ->gp_seq_needed. 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.
