-stable review patch. If anyone has any objections, please let us know. ------------------ From: NeilBrown At the point where this 'atomic_add' is, rdev could be NULL, as seen by the fact that we test for this in the very next statement. Further is it is really the wrong place of the add. We could add to the count of corrected errors once the are sure it was corrected, not before trying to correct it.
