Commit Message:

Line 8: 
Line 9: This patch doesn't change the behavior of MemoryStorageHandler.
Line 10: Instead, it changes the way we select storage domains for memory
Line 11: volumes to use filters. Each filter verifies that every domain meets a
Line 12: specific condition, and removes those who don't from the list of
s/who/that/
Line 13: candidates.
Line 14: This way, one can simply add a new filter to the list and add new logic
Line 15: to the domain selection.
Line 16:

This assumes both collections are the same type.
To be on the safe side, you should surround both with your own collection 
(e.g., new ArrayList<>)
