Description:
The badblocks routines we used from md have a bug where if a new range being
added overlaps with multiple distinct ranges, it only merges with the first one.
Consider the following operations:
badblocks_set(bb, 32, 1);
badblocks_set(bb, 34, 1);
badblocks_set(bb, 36, 1);
badblocks_show will now correctly report:
32 1
34 1
36 1
Now if I do:
badblocks_set(bb, 32, 12);
Ideally, this should collapse all ranges into a single (32, 12).. But
looks like badblocks_set only merges one set of adjacent mergeable
ranges, and then returns, resulting in:
32 3
36 1
Now if I add the same (32, 12) range again, I get:
32 5
as one more set is merged. And finally after adding (32, 12) one final
time, I get the expected
32 12.
