[Qemu-devel] [PATCH v4 0/4] Use blkdebug to make test deterministic

[Fam Zheng]

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.

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
