Hi Kevin, Hanna,

Here is a new version of iotests fixes from our s390x systems.
They aren't related, just came up walking through the failures.

I saw you asked Eric Blake about the nbd-in-qcow2-chain patch.
I left it as-is, but I am fine with skipping it if that's easier.

I added a new patch at the end of this series, which skips the last remaining
failure I can create out-of-the-box on s390. I had hoped that I could get
that one to work, but it doesn't appear to be trivial.

Regardless, I now get a clean run on an s390 host:

  Not run: 045 059 064 070 075 076 077 078 081 083 084 088 092 093 094 101 106 108 109 113 116 118 119 123 128 131 135 136 146 147 148 149 160 162 171 172 173 175 181 185 186 192 201 205 207 210 211 212 213 221 225 231 233 237 239 241 253 259 266 282 288 294 296 301 308 block-status-cache file-io-error fuse-allow-other fuse-mmap-shared fuse-truncate iothreads-nbd-export iov-padding loop-create-file luks-detached-header migration-permissions mirror-top-perms nbd-commands nbd-multiconn nbd-tls-iothread parallels-bitmap parallels-checks resize-below-raw vvfat write-zeroes-unmap zoned

  Passed all 261 iotests

I look forward to your feedback...
