Yep, I'll also set pvmw.ptl to NULL here if any corner cases arise.


This series already resides in mm-stable. I asked Andrew to remove it
for now. If that doesn't work, we'll need fixup patches to address any
review feedback.

I'll patiently wait Andrew's response, and then submit the next version or
fixup patches accordingly.

Well, which series are we talking about? "mm/madvise: enhance
lazyfreeing with mTHP in madvise_free v10" or ""Reclaim lazyfree THP
without splitting v4" or both?

See my other mail, "mm/madvise: enhance lazyfreeing with mTHP in madvise_free v10" is all acked/reviewed and good to go.


And how significant are the needed fixup patches?

And what is our confidence level after those fixups are in place?

I'm afraid I won't have time to review this series this/next week, so I cannot tell. I already assumed this would not be 6.10 material.
