This tests the functionality that was introduced in Linux 6.7 by kernel commit 5b1188847180 ("fscrypt: support crypto data unit size less than filesystem block size"). This depends on the xfsprogs patch "xfs_io/encrypt: support specifying crypto data unit size" (https://lore.kernel.org/r/20231013062639.141468-1-ebiggers@kernel.org) which adds the '-s' option to the set_encpolicy command of xfs_io. As usual, the test skips itself when any prerequisite isn't met. I've tested the new test on both ext4 and f2fs. Changed in v2: - Updated the cover letter, commit message, and a comment to reflect that the kernel commit that added this feature was merged in 6.7. - Rebased onto latest for-next branch of xfstests.
