4.4 futex: Change locking rules


Pavel Machek
 

Hi!

There was some discussion about futexes in 4.4 on irc.

https://lore.kernel.org/stable/20210309030605.3295183-2-zhengyejian1@huawei.com/

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.

Best regards,
Pavel
