+
+ * pass2.c (e2fsck_pass2): Fix the progress accounting so that we
+ get to 100%.
+
+ * pass3.c (e2fsck_pass3): Change progress accounting to be
+ consistent with the other e2fsck passes.
+
+ * e2fsck.c (e2fsck_run): At the end of each pass, call the
+ progress function with the pass number set to zero.
+
+ * unix.c (e2fsck_update_progress): If the pass number is zero,
+ ignore the call, since that indicates that we just want to
+ deallocate any progress structures.
