Hi Bart,
How about we create a generic helper in rc for creating null_blk
instance ?
This functionality is needed and pretty common, so that future
test-cases can reuse the code instead of duplicating code all over ?
e.g. For NVMe blktest category we have helpers for creating
subsystems/namespaces.
