+ * in the buffer if more recent than that current transaction then we
+ * need to attach the verifier directly. Failure to do so can lead to
+ * future recovery actions (e.g. EFI and unlinked list recovery) can
+ * operate on the buffers and they won't get the verifier attached. This
+ * can lead to blocks on disk having the correct content but a stale
+ * CRC.
+ *
+ * It is safe to assume these clean buffers are currently up to date.
+ * If the buffer is dirtied by a later transaction being replayed, then
+ * the verifier will be reset to match whatever recover turns that
+ * buffer into.
