But Long Li sent the patch which starts to use POST_INIT against
the net-next tree. If we apply this to net and Long Li's patch to
net-next

When a VF is being exposed form the kernel, it should be marked as "slave"
before exposing to the user-mode. The VF is not usable without netvsc running
as master. The user-mode should never see a VF without the "slave" flag.
An example of a user-mode program depending on this flag

When a VF is being exposed form the kernel, it should be marked as "slave"
before exposing to the user-mode. The VF is not usable without netvsc running
as master. The user-mode should never see a VF without the "slave" flag.

A perfect driver would only call dev_iommu_priv_set() from its probe
callback. We've made it functionally correct to call it from the of_xlate
by adding a lock around that call.
lockdep assert that iommu_probe_device_lock is held to discourage misuse.
