From: Monam Agarwal <monamagarwal123@xxxxxxxxx>
Subject: fs/proc/inode.c: use RCU_INIT_POINTER(x, NULL)
Replace rcu_assign_pointer(x, NULL) with RCU_INIT_POINTER(x, NULL)
The rcu_assign_pointer() ensures that the initialization of a structure is
carried out before storing a pointer to that 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)
