Specifying parameters on the kernel parameter line
Parameters that the kernel does not recognize as kernel parameters are ignored by the kernel and made available to user space programs.
One of these programs is modprobe, which Red Hat® Enterprise Linux® 8.6 uses to load modules for you. modprobe interprets module parameters that are specified on the kernel parameter line if they are qualified with a leading module prefix and a dot.
For example, you can include a specification with dasd_mod.dasd= on
the kernel parameter line. modprobe evaluates this specification as
the dasd= module parameter when it loads the dasd_mod
module.
