** Package changed: ubuntu => linux (Ubuntu) ** Description changed:
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.
