[PATCH] xfstests: add test 203, xfs_io bmap reallocation

To: xfs@xxxxxxxxxxx, Tomasz Majkowski <moosh009@xxxxxxxxx>
Subject: [PATCH] xfstests: add test 203, xfs_io bmap reallocation
From: Christoph Hellwig <hch@xxxxxxxxxxxxx>
Date: Fri, 20 Mar 2009 03:28:57 -0400
User-agent: Mutt/1.5.18 (2008-05-17)
Test that we can get all extent/hole information for files with more
than 16 extents and 15 holes which require a reallocation based on
XFS_IOC_FSGETXATTR.

Based on a testcase from Tomasz Majkowski <moosh009@xxxxxxxxx>.
