Linux kernel source tree
The value is now completely unused except for reporting it back through the F_GET_FILE_RW_HINT ioctl, so remove the value and the two ioctls for it. Trying to use the F_SET_FILE_RW_HINT and F_GET_FILE_RW_HINT fcntls will now return EINVAL, just like it would on a kernel that never supported this functionality in the first place.

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.
