This series adds a test for the functionality introduced by the kernel patch "fscrypt: support crypto data unit size less than filesystem block size" (https://lore.kernel.org/linux-fscrypt/20230925055451.59499-6-ebiggers@xxxxxxxxxx/). It is a ciphertext verification test, as opposed to general I/O test. This feature is not yet in mainline, but I've applied it for 6.7. The test depends on an xfsprogs patch that adds the '-s' option to the set_encpolicy command of xfs_io, allowing the new log2_data_unit_size field to be set via a shell script. As usual, the test skips itself when any prerequisite isn't met.
