When dump is copied to the filesystem in s390 format, follow on
'zgetdump -i' can fail with ioctl error:
# zgetdump /dev/dasdb1 -f s390 dump.s390
Format Info:
Source: s390_ext
Target: s390
Copying dump:
00000001 / 00008192 MB
00003688 / 00008192 MB
00006646 / 00008192 MB
00008192 / 00008192 MB
Success: Dump has been copied
# zgetdump -iVVVV dump.s390
zgetdump: Operation "BLKSSZGET" failed on "dump.s390" (Inappropriate ioctl for device)
Call ioctl(BLKSSZGET) only for s390_ext dump format (dump can be
stored on DASD partition only, not on the filesystem). For s390 format
a blocksize is not required for dump processing since s390 dump data is
not compressed.
Fixes: 271b809495 ("zdump/dfi_s390: Support reading compressed s390_ext dumps")
