[Qemu-block] [PATCH 00/17] iotests: don't choke on disabled drivers

[Roman Kagan]

Some iotests assume availability of certain block drivers, and fail if
the driver is not supported by QEMU because it was disabled at configure
time.

This series tries to address that, by making QEMU report the actual list
of supported block drivers in response to "-drive format=?", and using
this information to skip the parts of the io testsuite that can not be
run in this configuration.

Roman Kagan (17):
  block: iterate_format with account of whitelisting
  iotests: iotests.py: prevent deadlock in subprocess
  iotests: ask qemu for supported formats
  iotest 030: skip quorum test setup/teardown too
  iotest 030: require blkdebug
  iotest 055: skip unsupported backup target formats
  iotest 055: require blkdebug
  iotest 056: skip testcases using blkdebug if disabled
  iotest 071: notrun if blkdebug or blkverify is disabled
  iotest 081: notrun if quorum is disabled
  iotest 087: notrun if null-co is disabled
  iotest 093: notrun if null-co or null-aio is disabled
  iotest 099: notrun if blkdebug or blkverify is disabled
  iotest 124: skip testcases using blkdebug if disabled
  iotest 139: skip testcases using disabled drivers
  iotest 147: notrun if nbd is disabled
  iotest 184: notrun if null-co or throttle is disabled
