Add tests for fs-verity, a new feature for read-only file-based authenticity protection. fs-verity will be supported by ext4 and f2fs, and perhaps other filesystems later. Running these tests requires: - A kernel with the fs-verity patches from https://git.kernel.org/pub/scm/linux/kernel/git/tytso/fscrypt.git/log/ (should be merged in 4.21) and configured with CONFIG_FS_VERITY. - The fsverity utility program, which can be installed from https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/fsverity-utils.git/ - e2fsprogs v1.44.4-2 or later for ext4 tests, or f2fs-tools v1.11.0 or later for f2fs tests. Example with kvm-xfstests: $ kvm-xfstests -c ext4,f2fs -g verity See the file Documentation/filesystem/fsverity.rst in the kernel tree for more information about fs-verity.
