These pernet_operations register and unregister nf hooks, /proc entries, sysctl, percpu statistics. There are several global lists, and the only list modified without exclusive locks is ip_vs_conn_tab in ip_vs_conn_flush(). We iterate the list and force the timers expire at the moment. Since there were possible several timer expirations before this patch, and since they are safe, the patch does not invent new parallelism of their destruction. These pernet_operations look safe to be converted. Signed-off-by: Kirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
