    "content": "It starts from a \"make check\" failure on one of my private tree. The\nproblem is that when we do \"device_del\" we normally looking for two\nthings: one response (which is mostly empty), and a REMOVE event.  The\ntricky point is the event can either be there before/after the empty\nresponse.  So I added qmp_device_del() to make sure the order does not\nmatter, then use it where proper.\n\nSince I'm at it, I also added the sister helper qmp_device_add(), it\nhelps to remove LOCs.\n\nI still don't 100% sure why my private tree can trigger this error,\nwhile the master cannot. Anyway, I think this is something we should\nhave, no matter what.\n\nPlease review.  Thanks.\n\nPeter Xu (4):\n  libqtest: add qmp_device_del()\n  tests: use qmp_device_del() where proper\n  libqtest: add qmp_device_add()\n  tests: use qmp_device_add() where proper\n\n tests/libqos/pci.c        | 15 +++--------\n tests/libqos/usb.c        | 28 +++++----------------\n tests/libqtest.c          | 63 +++++++++++++++++++++++++++++++++++++++++++++++\n tests/libqtest.h          | 17 +++++++++++++\n tests/usb-hcd-uhci-test.c | 28 +++------------------\n tests/usb-hcd-xhci-test.c | 52 ++++----------------------------------\n 6 files changed, 97 insertions(+), 106 deletions(-)"
