Following are two bugfixes for md in current kernels.
The first is suitable for -stable is it can allow drive errors
through to the filesystem wrongly.
Both are suitable for 2.6.22.
Thanks,

[PATCH 001 of 2] md: Avoid a possibility that a read error can wrongly propagate through md/raid1 to a filesystem.
[PATCH 002 of 2] md: Improve the is_mddev_idle test
