[Qemu-devel] [PATCH v2 08/13] tests/test-blockjob: remove exit callback
Posted by John Snow 7 years, 2 months ago
We remove the exit callback and the completed boolean along with it.
We can simulate it just fine by waiting for the job to defer to the
main loop, and then giving it one final kick to get the main loop
portion to run.

Hm, well, sure, but I'd think deferred_to_main_loop is an internal
attribute.  Considering this is just a test, it doesn't matter, though, so:
