Subject: arch/x86: Use RCU_INIT_POINTER(x, NULL) in kvm/vmx.c
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3b63a43f1e04b935e1ce0383f78ac0f5c65433d8;p=linux-beck.git

arch/x86: Use RCU_INIT_POINTER(x, NULL) in kvm/vmx.c

Here rcu_assign_pointer() is ensuring that the
initialization of a structure is carried out before storing a pointer
to that structure.
So, rcu_assign_pointer(p, NULL) can always safely be converted to
RCU_INIT_POINTER(p, NULL).
