[Qemu-devel] [PATCH v5 0/4] Use blkdebug to make test deterministic

[Fam Zheng <famz@redhat.com>]

This adds "remove_break" command to block, which removes a break point defined
with "break". It is used in iotests.py to pause and resume drive in block job
cases to make the test deterministic.

v5: Addressing Max's comments (thanks for reviewing)
    [02] Resume all the requests.
    [03] Fix event="" case. Change default value to None.
         Change resume to bool.
    [04] Change resume to bool

v4: [01] Added.
    [03] Add common method pair "pause_drive" and "resume_drive".
    [04] Also fix 040, 055.

Fam Zheng (4):
  qemu-iotests: Drop local version of cancel_and_wait from 040
  blkdebug: add "remove_break" command
  qemu-iotest: Add pause_drive and resume_drive methods
  qemu-iotests: Make test case 030, 040 and 055 deterministic
