Paolo 'Blaisorblade' Giarrusso d7fb2c3865 [PATCH] uml ubd driver: change ubd_lock to be a mutex 
This lock protects ubd setup and teardown, so is only used in process context;
beyond that, during such setup memory allocations must be performed and some
generic functions which can sleep must be called (such as add_disk()).  So the
only correct solution is to make it a mutex instead of a spin_lock.  No other
change is done - this lock must be acquired in different places but it's done
afterwards.
