Message-ID: <1406712437-2184-1-git-send-email-wangxg.fnst@cn.fujitsu.com>

From: Xiaoguang Wang <wangxg.fnst@...fujitsu.com>

Subject: [PATCH v3] xfstests/ext4: regression test for wrong assert in ext4_mb_normalize_request()
Regression test for:
b5b6077 ext4: fix wrong assert in ext4_mb_normalize_request()
Meanwhile make minor changes to _scratch_mkfs_ext4() in common/rc, _scratch_mkfs_ext4()
might fail due to conflicts between being passed options and MKFS_OPTIONS. We fix this
by ignoring MKFS_OPTIONS if it fails the first time(see _scratch_mkfs_xfs()), as suggested
by Lukas Czerner.
