Message-Id: <1395471490-3025-1-git-send-email-monamagarwal123@gmail.com> Date: Sat, 22 Mar 2014 12:28:10 +0530 From: Monam Agarwal <monamagarwal123@...il.com> To: gleb@...nel.org, pbonzini@...hat.com, tglx@...utronix.de, mingo@...hat.com, hpa@...or.com, x86@...nel.org, kvm@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] 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).
