From: Anand Jain <Anand.Jain@xxxxxxxxxx>
This test case will test to confirm the replace works with
the failed (EIO) replacing source device. EIO condition is
achieved using the DM device.

v7->v8:
. Inline with the patch 1/3 v8 changes, use dmerror_mount()
v6->v7: accepts Dave's comments
. in line with changes as in 1/3 mainly the renames
v5->v6: accepts Eryu and Filipe's comments
. commit update
. correct cleanup with tmp.*
. don't redirect run_check $FSFTRESS_PROG to dev null
v4->v5: rebase on latest xfstests code and accepts Filipe comment
. cut line length to 80 char
. accommodate to the regression introduced by a092363bbdfa6cc6e44353136bae9d3aa81baae2
v3->v4: rebase on latest xfstests code
v2->v3: accepts Filipe Manana's review comments, thanks
. induce FS load using FSSTRESS_PROG, actually I missed it in v2
v1->v2: accepts Dave Chinner's review comments, thanks
. move 'start with the clean devices' code to actually at the
start of the script - damn why I didn't think like this before.
Thanks Dave.
. add .out file to contain the logs to verify.
