Hi Dave -
Here's the updated patchset for the rescan races. This fixes the issue
where we'd try to start multiple workers. It introduces a new "ready"
bool that we set during initialization and clear while queuing the worker.
The queuer is also now responsible for most of the initialization.
I have a separate patch set start that gets rid of the racy mess surrounding
the rescan worker startup. We can handle it in btrfs_run_qgroups and
just set a flag to start it everywhere else.
