I actually cc'd y ou partly because you were part of that earlier fix,
but also because of the implicit question:
"So it's very possible that the
if (IS_ENABLED(CONFIG_32BIT) || in_compat_syscall())
return 0;
test in __thp_get_unmapped_area() should be extended to take requested
address randomization into account"
and whether we maybe could do better?
For x86-64, the default for min compat bits is 28 - which is
presumably plenty - but maybe we have issues elsewhere?
