Revision efb55222d31c8c2af8b4ba42bb56b0b0beedf98e authored by Vladimir Oltean on 30 August 2019, 01:07:21 UTC, committed by David S. Miller on 01 September 2019, 01:45:34 UTC
taprio_init may fail earlier than this line: list_add(&q->taprio_list, &taprio_list); i.e. due to the net device not being multi queue. Attempting to remove q from the global taprio_list when it is not part of it will result in a kernel panic. Fix it by matching list_add and list_del better to one another in the order of operations. This way we can keep the deletion unconditional and with lower complexity - O(1).
