I've got a trivial patch teed up for late in the window that I wanted to
send in after Linus merges this pull. I was wondering whether you were
going to send in another x86/mm pull during the merge window (perhaps
without LAM in it?), or if this whole thing is going to wait for 6.3.
Either way is fine with me, but it'd save me a lot of F5 refreshing if I
knew what to expect.
