We don't need the RTNL lock for all operations on offload state. We only need to hold it around ndo calls. The device offload initialization doesn't require it. The soon-to-come querying of the offload info will only need it partially. We will also be able to remove the waitqueue in following patches. Use struct rw_semaphore because map offload will require sleeping with the semaphore held for read.

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.
