Patch 1 makes the VMDK driver to allocate multiple clusters at once. Earlier it used to allocate cluster by cluster which slowed down its performance to a great extent. Patch 2 changes the metadata update code to update the L2 tables for multiple clusters at once. Note: These changes pass all 41/41 tests suitable for VMDK driver.
