An iucv deadlock may occur, where one CPU is spinning on the iucv_table_lock for iucv_tasklet_fn(), while another CPU is holding the iucv_table_lock for an iucv_path_connect() and is waiting for the first CPU in an smp_call_function. Solution: replace spin_lock in iucv_tasklet_fn by spin_trylock and reschedule tasklet in case of non-granted lock. Signed-off-by:
