[PATCH v3] xfstests: Improve test 219 to work with different filesystems

To: xfs@xxxxxxxxxxx
Subject: [PATCH v3] xfstests: Improve test 219 to work with different filesystems
From: Jan Kara <jack@xxxxxxx>
Date: Wed, 29 Jun 2011 18:04:40 +0200
Cc: Jan Kara <jack@xxxxxxx>
Different filesystems account different amount of metadata in quota. Thus it is
impractical to check for a particular amount of space occupied by a file
because there is no right value. Change the test to verify whether the amount
of space is between the expected amount of space and the expected amount +5%.
The number of files is checked exactly as previously.
