Accept literal string "cancel" as resize operation and interpret that as a request to cancel the running operation. If it's running, wait until it finishes current work and return ECANCELED. Shrinking resize uses relocation to move the chunks away, use the conditional exclusive operation start and cancellation helpers.

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. 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.
