Yes, Geert also brought that up. As I mentioned there I took the text from your
commit message in commit 8bb227ac34c0 ("um: remove set_fs").
I didn't realize arch/um is for User Model Linux, I always thought um was just
some other processor! Next, I thought your comment 'used for User Mode Linux'
was just referring to userpsace.
Now I get it!
I will fix this up in v2.

You mean to just write as:
return size <= TASK_SIZE && addr <= TASK_SIZE - size;
I prefer keeping the braces around (TASK_SIZE - size).
