+Subject: batman-adv: Add missing include for in_interrupt()
+
+The fix for receiving (internally generated) bla packets outside the
+interrupt context introduced the usage of in_interrupt(). But this
+functionality is only defined in linux/preempt.h which was not included
+with the same patch.
+
+Fixes: 3747f81a1380 ("batman-adv: bla: use netif_rx_ni when not in interrupt context")
+Signed-off-by: Sven Eckelmann <sven@narfation.org>
