[PATCH] xfstests: add tests 281-283 for old xfsdump format

To: xfs@xxxxxxxxxxx
Subject: [PATCH] xfstests: add tests 281-283 for old xfsdump format
From: Bill Kendall <wkendall@xxxxxxx>
Date: Wed, 28 Mar 2012 15:09:40 -0500
Cc: Bill Kendall <wkendall@xxxxxxx>
Add three tests for verifying compatibility with xfsdump format 2.

Test 281 generates a format 2 dump and restores it.

Test 282 does a restore of a level 0 dump in the old dump format
followed by a restore of a level 1 dump in the current dump format.

Test 283 does a restore of a level 0 dump in the current dump format
followed by a restore of a level 1 dump in the old dump format.
