From ce9d1cdd618eaea256356c81cfd579039169b999 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Mon, 3 Jun 2013 13:40:36 -0500 Subject: [PATCH] xfstests 285: Fix test for ext4 in some configurations In some configurations (e.g. 1 KB block size), ext4 can decide it is better to zero out several blocks rather than splitting unwritten extent. This changes results SEEK_HOLE / SEEK_DATA returns and thus the test fails. Fix the problem by disabling the feature for this test.
