I've no objection to people taking patches independently, the concern is people
lagging on that and holding up a key conversion which is entirely mechanical, +
generally tree-wide stuff like this has been via the mm tree.
The mmap_prepare stuff is actually important for security (pertinent given
current AI fix storm) as it's by design super locked down vs. mmap which has
caused several genuine issues including a nasty 0-day.
So am keen to keep that rolling!
In this case each patch is mechanical and simple, so little surface area for
issues.
