/*-------------------------------------------------------------------------
* Function: test_multi_compat
*
* Purpose: Tests the backward compatibility for MULTI driver.
* See if we can open files created with v1.6 library.
* The source file was created by the test/file_handle.c
* of the v1.6 library. This test verifies the fix for
* Issue 2598. In v1.6 library, there was EOA for the whole
* MULTI file saved in the super block. We took it out in
* v1.8 library because it's meaningless for the MULTI file.
* v1.8 library saves the EOA for the metadata file, instead.
*
* Return: Success: 0
* Failure: -1
*
* Programmer: Raymond Lu
