Review Comment:
FYI, I agree that remove this condition from `shouldBeAvailable` does not
affect the fix of this bug. In order not to block this ticket, I added this
condition back. I am also willing to help improve or refactor it, looking
forward to a clearer and easier to understand `LocalBufferPool`.
