[Qemu-block] [PATCH v6 0/5] Improve I/O tests coverage of LUKS driver

[Daniel P. Berrange]

The main goal of this series is to get the I/O tests passing
100% with LUKS when run with './check -luks'. It also adds a
few more combinations to the LUKS/dmcrypt interoperability
test.

To make LUKS testing not quite as slow, we drop the PBKDF
iteration count down to a very small value. This doesn't
remove all overhead, as formatting the volume will always
measure PBKDF timing over a 1 second interval.

Changed in v6:

 - Fix quoting of $TEST_IMG (Eric/Max)
 - Remove accidental use of tabs (Max)
 - Drop unused SYSEMU_EXTRA_ARGS (Max)
 - Remove accidental import of 'time' module (Max)

Changed in v5:

 - Rebase to kevin/block  git tree instead of master
 - Fix LUKS compat in new test 181

Changed in v4:

 - Fix misc mistakes in syntax conversion (Max)
 - Drop changes to 120 & mark it unsupported (Max)
 - Use _unsupported_fmt (Max)

Changed in v3:

 - Fix some typos in commit message(s) (Eric)

Changed in v2:

 - Split off patch that change check.time recording since
   it was not a direct dependancy
 - Skip new 159 & 170 tests which don't work due to qemu-img
   dd limitations

Daniel P. Berrange (5):
  iotests: skip 159 & 170 with luks format
  iotests: fix remainining tests to work with LUKS
  iotests: reduce PBKDF iterations when testing LUKS
  iotests: add more LUKS hash combination tests
  iotests: chown LUKS device before qemu-io launches
