Robert Baldyga fd489e3a30 Fix potential deadlock in discard ... HB lock takes inclusive metadata lock, which is taken also by metadata flush, thus trying to call metadata flush under HB lock attempts to take this lock recursively. In that case, if in the meantime some other thread would try to take exclusive metadata lock, the inner inclusive lock would block (because the lock keeps the order), with outer inclusive lock still held, leading to a deadlock.
