Subject: [xfstests PATCH v5 1/5] ext4: allow ext4 to use $SCRATCH_LOGDEV
Date: Fri, 16 Jun 2017 15:36:15 -0400	[thread overview]
Message-ID: <20170616193619.14576-2-jlayton@redhat.com> (raw)
In-Reply-To: <20170616193619.14576-1-jlayton@redhat.com>

The writeback error handling test requires that you put the journal on a
separate device. This allows us to use dmerror to simulate data
writeback failure, without affecting the journal.

xfs already has infrastructure for this (a'la $SCRATCH_LOGDEV), so wire
up the ext4 code so that it can do the same thing when _scratch_mkfs is
called.
