As part of an effort to clean up fscrypt-related error codes, make FS_IOC_SET_ENCRYPTION_POLICY fail with EEXIST when the file already uses a different encryption policy. This is more descriptive than EINVAL, which was ambiguous with some of the other error cases. I am not aware of any users who might be relying on the previous error code of EINVAL, which was never documented anywhere. This failure case will be exercised by an xfstest.

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.
