/*
* History:
* 93/05/26 - Creation from e2fsck
* 94/02/27 - Made a separate bad blocks checker
+ * 99/06/30...99/07/26 - Added non-destructive write-testing,
+ * configurable blocks-at-once parameter,
+ * loading of badblocks list to avoid testing
+ * blocks known to be bad, multiple passes to
+ * make sure that no new blocks are added to the
+ * list. (Work done by David Beattie)
