Subject: [PATCH 2/7] blivet/zfcp: remove code broken since zfcp automatic LUN
scan
The old existing test preceding the removed code was only designed for the
old zfcp before it got automatic LUN scan. Hence, the test is incomplete.
With zfcp auto LUN scan, zfcp can just have SCSI devices without any
zfcp unit representation in sysfs.
Do not bother cleaning up an unused FCP device and just remove the code.
Note: Do not confuse zfcp auto port scan with zfcp auto LUN scan.

Subject: [PATCH 4/7] blivet/zfcp: change to consolidated persistent device
config by zdev (#1802482,#1937049)
Implements the zfcp part of referenced bugs.
https://github.com/ibm-s390-linux/s390-tools/tree/master/zdev/
handles everything as of
ibm-s390-linux/s390-tools@06a30ae
("zdev/dracut: add rd.zfcp cmdline option handling").
It is no longer necessary to perform individual pre-req steps, such as
setting an FCP device online, when we want to attach a LUN. Just call
chzdev to configure zfcp LUNs and let it do what is necessary, including
cio_ignore handling and udev settle.
The spec file update reflects the new dependency on `chzdev` from the
s390 architecture specific sub-package s390utils-core. Actually, this
commit here only depends on `chzdev` in older versions already packaged
and shipped, so no version comparison necessary here.
Since chzdev now implicitly sets the FCP device online
and there is no more preceding explicit FCP device online,
move the path over-specification warning after the call to chzdev.
Otherwise, the FCP device could still be offline and its
port_type unknown, so has_auto_lun_scan() would get wrong information
regarding the port_type being NPIV.
Anaconda handles the persistent config of all s390 device types as of
commit ("write persistent config of any (dasd,zfcp,znet) s390 devices to
sysroot"), so drop the special handling in zfcp.write().

Subject: [PATCH 5/7] blivet/zfcp: remove no longer used read_config
functionality (#1802482,#1937049)
Implements the zfcp part of referenced bugs.
Since
https://github.com/rhinstaller/anaconda/commit/87ab1ab2a3aa8b95cd75b2f37e0881e5f57656a5
("Support cio_ignore functionality for zFCP devices (#533492)"),
/etc/zfcp.conf replaced /tmp/fcpconfig.
Since
https://github.com/rhinstaller/anaconda/commit/011ea0a1779459ed20990ddf52166aa75a9c1382
("Remove linuxrc.s390"), /etc/zfcp.conf only exists if the user specified
dracut cmdline parameter rd.zfcp=.
https://github.com/ibm-s390-linux/s390-tools/tree/master/zdev/
handles parsing of rd.zfcp= without /etc/zfcp.conf as of
https://github.com/ibm-s390-linux/s390-tools/commit/06a30ae529a5d6ad2369ed81da056bf3a6147bb6
("zdev/dracut: add rd.zfcp cmdline option handling").
https://src.fedoraproject.org/rpms/s390utils.git
no longer writes /etc/zfcp.conf during deprecated parsing of rd.zfcp=
as of commit
("zfcp: migrate to consolidated persistent device config with zdev")
Hence, nothing populates /etc/zfcp.conf during installer boot anymore.
Anaconda imports configuration for all s390 device types as of
commit ("write persistent config of any (dasd,zfcp,znet) s390 devices to
sysroot"). The only remaining import source is from dracut boot parameters.

Subject: [PATCH 7/7] DASDDevice: dracut_setup_args() without deprecated
dasd.conf (#1802482,#1937049)
Implements the dasd part of referenced bugs.
Depends on
ibm-s390-linux/s390-tools@689b894
("zdev: add helper to convert from zdev config to dasd_mod.dasd").
The spec file update reflects the new dependency on `zdev-to-dasd_mod.dasd`
in the new v2.31.0 of the s390 architecture specific sub-package
s390utils-core.
Delegate the generation of rd.dasd statements to a helper tool from
s390-tools, which gets its low-level config information from the
consolidated persistent configuration mechanism using chzdev.
