Store the blocks in the form of a n-ary tree structure. ( i.e. every sub block of a block stored as a child).

1.Initially a block( say Block1) is locked.
2.Next when another block( say Block2) needs to be locked, find the common ancestor(say Block3) of Block1 and Block2.
3. If (Block3==Block1) or (Block3==Block2)
then dont grant lock to Block2.
else
grant lock to Block2.
