Subject: RE: [PATCH] drivers/net/wireless: Use RCU_INIT_POINTER(x, NULL) in
 iwlwifi/mvm/sta.c

> 
> This patch replaces rcu_assign_pointer(x, NULL) with RCU_INIT_POINTER(x,

> 
> The rcu_assign_pointer() ensures that the initialization of a structure

> And in the case of the NULL pointer, there is no structure to initialize.
> So, rcu_assign_pointer(p, NULL) can be safely converted to
> RCU_INIT_POINTER(p, NULL)
