Add parsing of dracut cmdline option "rd.zfcp=..." at initrd runtime. It delegates configuration to chzdev. Implement `dracut --print-cmdline` and `dracut --hostonly-cmdline` for initrd build time. Emit an rd.zfcp option for each zfcp-attached SCSI disk in dracut's device dependency graph (to mount the root-fs, or to access the kdump target). This allows a distribution independent device configuration. Configuration is consistent by using chzdev as backend. It also prevents duplicate activations of the same device. Along with the existing functionality of zdev/dracut, it makes the following dracut modules superfluous: https://github.com/dracutdevs/dracut/tree/master/modules.d/95zfcp [rd.zfcp.conf is no longer needed and thus ignored here; the preceding ("zdev/dracut: fix marking hostonly files so delete option works") makes rd.hostonly=0 work as a generic replacement] https://github.com/dracutdevs/dracut/tree/master/modules.d/95zfcp_rules Github-ID: https://github.com/ibm-s390-linux/s390-tools/pull/158 Acked-by: Vineeth Vijayan <vneethv@linux.ibm.com> Acked-by: Peter Oberparleiter <oberpar@linux.ibm.com> Signed-off-by: Steffen Maier <maier@linux.ibm.com> Signed-off-by: Jan Höppner <hoeppner@linux.ibm.com>
