dm: use noio when sending kobject event ...
commit 6958c1c640af8c3f40fa8a2eee3b5b905d95b677 upstream.
kobject_uevent may allocate memory and it may be called while there are dm
devices suspended. The allocation may recurse into a suspended device,
causing a deadlock. We must set the noio flag when sending a uevent.
The observed deadlock was reported here:
