A user reported a regression with using the normal ioctl interface on
newer kernels. This happens because I was setting the device size
before the device was actually connected, which caused us to error out
and close everything down. This didn't happen on netlink because we
hold the device lock the whole time we're setting things up, but we
don't do that for the ioctl path. This fixes the problem.

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.
