There was some discussion about futexes in 4.4 on irc. https://lore.kernel.org/stable/20210309030605.3295183-2-zhengyejian1@huawei= =2Ecom/ I don't believe we need to do anything there. Peter Zijlstra is re-doing locking for futexes, which will have benefits for future realtime releases. But we have separate patches for 4.4-rt, so we should be fine.
