# Note that the reference output intentionally includes the 'offset' field in
# BLOCK_JOB_* events for all of the following block jobs. They are predictable
# and any change in the offsets would hint at a bug in the job throttling code.
#
# In order to achieve these predictable offsets, all of the following tests
# use speed=65536. Each job will perform exactly one iteration before it has
# to sleep at least for a second, which is plenty of time for the 'quit' QMP
# command to be received (after receiving the command, the rest runs
# synchronously, so jobs can arbitrarily continue or complete).
#
# Jobs present while QEMU is terminating iterate once more due to
# bdrv_drain_all().
#
# The buffer size for commit and streaming is 512k (waiting for 8 seconds after
# the first request), for active commit and mirror it's large enough to cover
# the full 4M, and for backup it's the qcow2 cluster size, which we know is
# 64k. As all of these are at least as large as the speed, we are sure that the
# offset advances exactly twice before qemu exits.
