Message-Id: <1395600267-9169-1-git-send-email-monamagarwal123@gmail.com> Date: Mon, 24 Mar 2014 00:14:27 +0530 From: Monam Agarwal <monamagarwal123@...il.com> To: trond.myklebust@...marydata.com, linux-nfs@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] fs: Use RCU_INIT_POINTER(x, NULL) in nfs/delegation.c This patch replaces 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) Signed-off-by: Monam Agarwal <monamagarwal123@...il.com> --- fs/nfs/delegation.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/nfs/delegation.c b/fs/nfs/delegation.c index 5d8ccec..349e63b 100644 --- a/fs/nfs/delegation.c +++ b/fs/nfs/delegation.c @@ -249,7 +249,7 @@ nfs_detach_delegation_locked(struct nfs_inode *nfsi, list_del_rcu(&delegation->super_list); delegation->inode = NULL; nfsi->delegation_state = 0; - rcu_assign_pointer(nfsi->delegation, NULL); + RCU_INIT_POINTER(nfsi->delegation, NULL); spin_unlock(&delegation->lock); return delegation; } -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
