If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags

New smatch warnings:
drivers/vhost/vhost.c:241 vhost_worker_queue() error: we previously assumed 'worker' could be null (see line 241)

I only meant to send this warning.

Old smatch warnings:
drivers/vhost/vhost.c:311 vhost_dev_flush() warn: iterator 'i' not incremented
drivers/vhost/vhost.c:678 vhost_attach_cgroups() error: uninitialized symbol 'ret'.
drivers/vhost/vhost.c:673 vhost_attach_cgroups() warn: iterator 'i' not incremented

Not these.  I need to fix these for systems without the cross function
DB...  #embarassing.
