[PATCH 0/2] md: Add consistency check feature for level-1 RAID

This patch series introduces an online consistency check for RAID-1
md-arrays.
The feature compares each block that is read with its pendants on the
other array members to detect silent data corruption (a.k.a. bit rot).
Unfortunately, the feature is not fully-functional at this point, as we
have reached a dead end (see below).
We still want to hand in the patch for reference; maybe you can help
us, for we plan to keep on working on it.

The following issues remain:

- Partitions cannot be mounted with enabled safe read for some reason
(We suppose something goes wrong when duplicating the bio structure)
- Broken sectors during a read result in a crash
- There may be synchronization issues

The following patches apply to the linux-next tree
(rev ed87ead565a6130174fc27a46af65169cbff7677).
