In testing we noticed that nbd would spew if you ran a fio job against the raw device itself. This is because fio calls a block device specific ioctl, however the block layer will first pass this back to the driver ioctl handler in case the driver wants to do something special. Since the device was setup using netlink this caused us to spew every time fio called this ioctl. Since we don't have special handling, just error out for any non-nbd specific ioctl's that come in. This fixes the spew. Signed-off-by: Josef Bacik <jbacik@fb.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
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.
