commit 6a4bc44b012cbc29c9d824be2c7ab9eac8ee6b6f upstream. The neighbor compare API implementation for B.A.T.M.A.N. V checks whether the neigh_ifinfo for this neighbor on a specific interface exists. A warning is printed when it isn't found. But it is not called inside a lock which would prevent that this information is lost right before batadv_neigh_ifinfo_get. It must therefore be expected that batadv_v_neigh_(cmp|is_sob) might not be able to get the requested neigh_ifinfo. A WARN_ON for such a situation seems not to be appropriate because this will only flood the kernel logs. The warnings must therefore be removed.

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.
