Hi,
This series failed the docker-quick@centos7 build test. Please find the testing
commands and
their output below. If you have Docker installed, you can probably reproduce it
locally.
=== TEST SCRIPT BEGIN ===
#!/bin/bash
make docker-image-centos7 V=1 NETWORK=1
time make docker-test-quick@centos7 SHOW_ENV=1 J=14 NETWORK=1
=== TEST SCRIPT END ===
Not run: 259
Failures: 190
Failed 1 of 117 iotests
Hmm - the email truncated the useful part of the failure. Anyways,
reading from...
The full log is available at

which looks suspiciously like an uninitialized variable leaking through
when there are no bitmaps to be measured. I'll fix it in v2.
