generic_swapfile_activate() doesn't allow holes, so we should be consistent here. This is also a bit safer: if the user creates a swapfile with, say, truncate -s $SIZE followed by mkswap, they should really get an error and not much less swap space than they expected. swapon(8) will error out before calling swapon(2) if the file has holes, anyways.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ 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.
