From c730c90316aa5753c6b2d3d5af40085c220e3a91 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Mon, 27 Oct 2014 17:13:31 +0100 Subject: mac802154: rx: document ieee802154_rx() context requirement This patch is similar like d20ef63d32461332958661df73e21c0ca42601b0 ("mac80211: document ieee80211_rx() context requirement"). The netif_receive_skb call requires with softirqs disabled. This patch adds a warning if softirqs are pending while calling ieee802154_rx.
