Subject: [dhowells-fs:iov-extract] [iov_iter] 64ea9d6c5f:
 blktests.zbd/(003/004).fail blktests.loop/(002/004).fail

To reproduce:

        git clone https://github.com/intel/lkp-tests.git
        cd lkp-tests
        sudo bin/lkp install job.yaml           # job file is attached in this email
        bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
        sudo bin/lkp run generated-yaml-file

        # if come across any failure that blocks the test,
        # please remove ~/.lkp and /lkp dir to run from a clean state.
