I just queued some test jobs for it.

% queue -q vip -t ivb44 -b hch-vfs/iomap-fixes aim7-fs-1brd.yaml fs=xfs -r3 -k fe9c2c81ed073878768785a985295cbacc349e42 -k ca2edab2e1d8f30dda874b7f717c2d4664991e9b -k 99091700659f4df965e138b38b4fa26a29b7eade

That job file can be found here:

        https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/tree/jobs/aim7-fs-1brd.yaml

It specifies a matrix of the below atom tests:

        wfg /c/lkp-tests% split-job jobs/aim7-fs-1brd.yaml -s 'fs: xfs'

        jobs/aim7-fs-1brd.yaml => ./aim7-fs-1brd-1BRD_48G-xfs-disk_src-3000-performance.yaml
        jobs/aim7-fs-1brd.yaml => ./aim7-fs-1brd-1BRD_48G-xfs-disk_rr-3000-performance.yaml

        jobs/aim7-fs-1brd.yaml => ./aim7-fs-1brd-1BRD_48G-xfs-disk_wrt-3000-performance.yaml

        jobs/aim7-fs-1brd.yaml => ./aim7-fs-1brd-1BRD_48G-xfs-disk_rd-9000-performance.yaml

If you see other suitable tests for this patch, feel free to drop me a
hint.  I'v queued these jobs to the other machines to make them run in
parallel.
