Trying to do "lkp run job.yaml" doesn't work:

/root/lkp-tests/filters/need_kconfig.rb:20:in `read_kernel_kconfigs': .config doesn't exist: /pkg/linux/x86_64-rhel-8.3/gcc-13/b4834f12a4df607aaedc627fa9b93f3b18f664ba/.config (Job::ParamError)

I tried to run the filebench directly, but that only wants to hammer on
/tmp/bigfileset/ and also wants a file for SHM precreating in /tmp.  I was
able to get it to work with cifs by:

touch /tmp/filebench-shm-IF6uX8
truncate -s 184975240 /tmp/filebench-shm-IF6uX8
mkdir /tmp/bigfileset
mount //myserver/test /tmp/bigfileset/ -o user=shares,pass=...,cache=loose

/root/lkp-tests/programs/filebench/pkg/filebench-lkp/lkp/benchmarks/filebench/bin/filebench -f /lkp/benchmarks/filebench/share/filebench/workloads/filemicro_seqwriterandvargam.f

It tries to remove /tmp/bigfileset/, can't because it's mounted, and then
continues anyway.

It should be easier than this ;-)
