[ Upstream commit0c1cc8b221] When calling add/remove VXLAN port, a lock must be held in order to prevent race scenarios when more than one add/remove happens at the same time. Fix by holding our state_lock (mutex) as done by all other parts of the driver. Note that the spinlock protecting the radix-tree is still needed in order to synchronize radix-tree access from softirq context.

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.
