Hi!
> [CCing Cyril]

Ah I've confused the vm_flags and flags variables and nobody caught that
during the review. But still sorry that I've messed up.

Looking at the code I agree with Michal that we try to find the
intesection poinlesly even for !MAP_FIXED which slowns down mmap() tiny
little bit which should be fixed.

The fix looks good to me.
