Have you been running with blk-mq?
Either by setting CONFIG_DM_MQ_DEFAULT or:
echo Y > /sys/module/dm_mod/parameters/use_blk_mq

I'm seeing test_02_sdev_delete fail with blk-mq enabled.

(and with my latest DM mpath code I'm testing for Linux 4.6: I'm seeing
a nasty deadlock from test_01_sdev_offline... so that's "fun")

After upgrading fio to latest fio.git I no longer see fio validate
errors.

Yes, I'm using a comparable setup.  But with localmodconfig.
