Linux-zen 5.15.2 no longer has futex2

Um, there was a regression or something? I remember that on linux-zen-5.14.x the logs showed futex2 up and running but now on 5.15.2 it only shows fsync up and running, do any of you knows if this is a bug or if it was just a rename thing? thanks in advice

Maybe something in relation to this postponed support?

thanks for the reply, but I think this article refers to the mainline kernel as the author mentions that 5.15 is "another kernel that will lack FUTEX2", and I just rebooted to check and linux-zen-5.14.16 has futex2.

or maybe the futex2 patches on linux-zen were the simple ones mentioned

I see, you're right.
Anyway also on the zen side there seem to have been regressions and issues on this futex2 in the past, so this could be a new one.
Anyway, I'm not a gamer nor a technical expert, so I give up :blush:
