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@xxxxxxxxx> --- net/mac80211/ibss.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/net/mac80211/ibss.c b/net/mac80211/ibss.c index e458ca0..cb262c4 100644 --- a/net/mac80211/ibss.c +++ b/net/mac80211/ibss.c @@ -253,7 +253,7 @@ static void __ieee80211_sta_join_ibss(struct ieee80211_sub_if_data *sdata, presp = rcu_dereference_protected(ifibss->presp, lockdep_is_held(&sdata->wdev.mtx)); - rcu_assign_pointer(ifibss->presp, NULL); + RCU_INIT_POINTER(ifibss->presp, NULL); if (presp) kfree_rcu(presp, rcu_head); -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
