Hi
The test shell/integrity.sh creates raid arrays, corrupts one of the
legs, then reads the array and verifies that the corruption was
corrected. Finally, the test tests that the number of mismatches on the
corrupted leg is non-zero.
The problem is that the raid1 implementation may freely choose which leg
to read from. If it chooses to read from the non-corrupted leg, the
corruption is not detected, the number of mismatches is not incremented
and the test reports this as a failure.
Fix the test by not checking the number of integrity mismatches for
raid1.
