An md/raid6 data corruption bug
Neil Brown, the MD maintainer, has sent out an alert for a bug which, in
fairly abnormal conditions, can lead to data loss on an MD-hosted RAID6
array. "There is no risk to an optimal array or a singly-degraded
array. There is also no risk on a doubly-degraded array which is not
recovering a device or is not receiving write requests." RAID6
users will likely want to apply the patch, though, which is likely to show
up in the next stable kernel update from distributors.
