md allows a new array device to be created by simply opening a device file. This make it difficult to remove the device and udev is likely to open the device file as part of processing the REMOVE event. There is an alternate mechanism for creating arrays by writing to the new_array module parameter. When using tools that work with this parameter, it is best to disable the old semantics. This new module parameter allows that. Signed-off-by: NeilBrown <neilb@suse.com> Acted-by: Coly Li <colyli@suse.de> Signed-off-by: Shaohua Li <shli@fb.com>
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.
