Hi, I am looking for a way to test whether I am running in a bottom half context or user context. There are kernel functions which may be called from both user and bottom half contex. For eg, tcp_transmit_skb, may be called from user context for first time transmission of a packet or from the timer bottom half in case of retransmission. Is there a way to check within that function whether it is currently running in user / bottom half context?
Any hints greatly appreciated ! Regards,
