The current KVDL allocation API allows the user to specify the requested number of entries, but the user has no way of knowing how many entries were actually allocated. This works because existing users (e.g., router) request the exact number they end up using. With the introduction of large adjacency groups, this will change, as the router will have the ability to choose from several allocation sizes, where larger allocations provide higher accuracy with respect to requested weights and better resilience against nexthop failures. One option is to have the router try several allocations of descending size until one succeeds, but a better way is to simply allow it to query the actual allocation size and then size its request accordingly.

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.
