Message-Id: <1395520349-3033-1-git-send-email-monamagarwal123@gmail.com> Date: Sun, 23 Mar 2014 02:02:29 +0530 From: Monam Agarwal <monamagarwal123@...il.com> To: drbd-dev@...ts.linbit.com, drbd-user@...ts.linbit.com, linux-kernel@...r.kernel.org Subject: [PATCH] drivers/block: Use RCU_INIT_POINTER(x, NULL) in drbd/drbd_state.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> --- drivers/block/drbd/drbd_state.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/block/drbd/drbd_state.c b/drivers/block/drbd/drbd_state.c index 216d47b..a45a0d3 100644 --- a/drivers/block/drbd/drbd_state.c +++ b/drivers/block/drbd/drbd_state.c @@ -1547,7 +1547,7 @@ static int w_after_conn_state_ch(struct drbd_work *w, int unused) old_conf = tconn->net_conf; tconn->my_addr_len = 0; tconn->peer_addr_len = 0; - rcu_assign_pointer(tconn->net_conf, NULL); + RCU_INIT_POINTER(tconn->net_conf, NULL); conn_free_crypto(tconn); mutex_unlock(&tconn->conf_update); -- 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/
