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/chan.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/net/mac80211/chan.c b/net/mac80211/chan.c index bd1fd8e..b297bd3 100644 --- a/net/mac80211/chan.c +++ b/net/mac80211/chan.c @@ -392,7 +392,7 @@ static void ieee80211_unassign_vif_chanctx(struct ieee80211_sub_if_data *sdata, lockdep_assert_held(&local->chanctx_mtx); ctx->refcount--; - rcu_assign_pointer(sdata->vif.chanctx_conf, NULL); + RCU_INIT_POINTER(sdata->vif.chanctx_conf, NULL); sdata->vif.bss_conf.idle = true; -- 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
