The function job_cancel_async() will always cause an assert for blockjob
|
|
|
ae23c9 |
user resume. We set job->user_paused to false, and then call
|
|
|
ae23c9 |
job->driver->user_resume(). In the case of blockjobs, this is the
|
|
|
ae23c9 |
block_job_user_resume() function.
|
|
|
ae23c9 |
|
|
|
ae23c9 |
In that function, we assert that job.user_paused is set to true.
|
|
|
ae23c9 |
Unfortunately, right before calling this function, it has explicitly
|
|
|
ae23c9 |
been set to false.
|
|
|
ae23c9 |
|
|
|
ae23c9 |
The fix is pretty simple: set job->user_paused to false only after the
|
|
|
ae23c9 |
job user_resume() function has been called.
