NeilBrown 235549605e md/raid1: Don't use next_resync to determine how far resync has progressed ... next_resync is (approximately) the location for the next resync request. However it does *not* reliably determine the earliest location at which resync might be happening. This is because resync requests can complete out of order, and we only limit the number of current requests, not the distance from the earliest pending request to the latest. mddev->curr_resync_completed is a reliable indicator of the earliest position at which resync could be happening. It is updated less frequently, but is actually reliable which is more important. So use it to determine if a write request is before the region being resynced and so safe from conflict. This error can allow resync IO to interfere with normal IO which could lead to data corruption. Hence: stable.
