Description

GridCacheOffheapManager.recreateCacheDataStore() calls updatePartitionCounter() under partStoreLock which may try to acquire checkpointReadLock.

recreateCacheDataStore() method can be called with checkpointReadLock (on GridDhtPartitionsExchangeFuture.updatePartitionFullMap)
or without checkpointReadLock (GridDhtPartitionEvictor thread calls evictPartitionAsync),

So, checkpoint can cause a deadlock if it happens in between.

Seems, we should acquire checkpointReadLock before partStoreLock.
