The expected case is when the last xattr with a totl key is removed that the count and value both reach zero. In case of a mismatch or corrupted value, we have several different failure modes: - count zero, value non-zero - value zero, count non-zero - both non-zero The first case is the easiest to resolve, which is what this patch does - it drops it and prints an error. The other cases are more difficult and need a manual method to erase the stale key, and one would have to scan the entire namespace to make sure that the xattrs are indeed all removed.
