James,
could you pick up this fix, please?
Btw., it looks like others where bitten by this one:
https://nazar.karan.org/blob/distro!
parted.git/8780c767126938173f49dfbcd4360813932f7756/SOURCES!
disable-t9020.patch
Thanks,
Martin
Both start_sect and nr_sects in struct partition are __le32 and
require cpu_to_le32() on assignment.
Without this fix tools like fdisk show an invalid partition table
for SCSI devices emulated by scsi_debug on big-endian architectures,
like s390x. Besides a kernel message like this was emitted:
sda: p1 start 536870912 is beyond EOD, enabling native capacity
sda: p1 start 536870912 is beyond EOD, truncated
For verification 'xxd -l 512 /dev/sda' has been used to make sure
that this fix makes scsi_debug generated partition tables on s390x
look like the ones generated on my laptop.
