When the "test_dummy_encryption" mount option is specified, the fs-verity file corruption test generic/574 is flaky; it fails about 1% of the time. This happens because in the three test cases where a single byte of the test file is corrupted, sometimes the new byte happens to be the same as the original. This is specific to test_dummy_encryption because the encrypted data is nondeterministic (and appears random), unlike the unencrypted data. Fix this by corrupting 5 bytes instead of 1, so that the probability of failure becomes effectively zero. Signed-off-by: Eric Biggers <ebiggers@google.com>
