SandeepKsinha af11c397fd md linear: Protecting mddev with rcu locks to avoid races 
Due to the lack of memory ordering guarantees, we may have races around
mddev->conf.

In particular, the correct contents of the structure we get from
dereferencing ->private might not be visible to this CPU yet, and
they might not be correct w.r.t mddev->raid_disks.

This patch addresses the problem using rcu protection to avoid
such race conditions.
