[Qemu-devel] [PATCH 1/4] block: cancel jobs when a device is ready to go away

[Paolo Bonzini]

We do not want jobs to keep a device busy for a possibly very long
time, and management could become confused because they thought a
device was not even there anymore.  So, cancel long-running jobs
as soon as their device is going to disappear.
