Subject: [PATCH 9/9] zipl: Fix zfcpdump "struct job_ipl_data" initialization
Description: zipl: Fix zfcpdump "struct job_ipl_data" initialization
Symptom: When zfcpdump starts, dump fails and the following error
message is written:
ERROR: open() source device '/sys/kernel/debug/zcore/mem' failed!
Problem: Because the "struct job_ipl_data" stack variable is not
initialized in add_dump_program() the "is_kdump" member can
be non-zero in case of zfcpdump. This makes the zfcpdump
code think that stand-alone kdump is triggered instead of
zfcpdump and then "zcore/mem" is not created by the kernel.
Solution: Initialize "struct job_ipl_data" with zeroes.
Reproduction: 1) Prepare SCSI disk with zipl:
# mount /dev/sda1 /mnt
# zipl -D /dev/sda1 -t /mnt
2) Trigger SCSI dump
Note: Because the problem occurs only if the stack variable is
not zero the problem will not occur every time.
