iotest 226 does not cope well with being unable to lock /dev/null and creates a lot of spurious errors.
Backport fixes from upstream to quell them on certain kernel configurations.
Fix included in qemu-kvm-rhev-2.12.0-27.el7
Run test 226 on qemu-kvm-rhev-2.12.0-27.el7, it passed. Set bug's status to "Verified".
