I was hoping we could re-enable VMA locks in 6.4 once we get more confirmations that the problem is gone. Is that not possible once the BROKEN dependency is merged?
I think "no". By doing this we're effectively backporting a minor performance optimization, which isn't a thing we'd normally do.
In that case, maybe for 6.4 we send the fix and only disable it by default without marking BROKEN? That way we still have a way to enable it if desired?
I'm preparing the next version with Liam's corrections. If the above option I suggested is acceptable I can send a modified second patch which would not have BROKEN dependency.
I think just mark it broken and move on. At some later time we can consider backporting the fixes into 6.4.x and reenabling, but I don't think it's likely that we'll do this.
